UnStuffed Pepper Casserole with a Fresh Twist
It’s true that the flavors of Italian stuffed peppers really can’t be beat (this top-rated slow cooker stuffed pepper soup for example is top-notch), and I will say this new take on stuffed pepper (or should I say ‘unstuffed’?) casserole is truly a winner! It takes the classic stuffed pepper idea and turns it into an easy 1-pot casserole that feels just as hearty and loaded, but also filled with fresh, whole ingredients.
In testing this recipe, I found that a lot of other stuffed pepper casserole recipes were really rice-heavy, which doesn’t let the main ingredients (ahem, the red and green peppers and meat) shine. In my fresher version, I use less rice and a whole lot more veggies (4 bell peppers, to be exact!) and the results remind me so much more of stuffed peppers, plus you get extra veggies, which is always a plus. And, since everything cooks together in one pot on the stove, there’s no need to pre-bake the peppers, or cook the rice separately, and you know I love simplifying classic recipes.
That’s right! After sautéing the sliced peppers and ground beef in a large pot, add the remaining ingredients (except the cheese) and cover the pot to let the rice cook. In the last couple minutes of cooking, sprinkle the beefy, vegetable-packed casserole with a bit of shredded cheese for good measure, so there’s just enough to give that melty, gooey feel without going overboard. Top it off with some chopped parsley for color and freshness and then dig in! And for nights when you’d rather skip the oven, my one-pot sausage and pepper pasta comes together on the stovetop in about 30 minutes.

Welcome to My Kitchen, Let’s Make Stuffed Pepper Casserole






Testing Notes from My Kitchen for Beef Pepper Casserole
- Peppers: I used 2 red bell peppers and 2 green bell peppers, but you can use all green, all red, or a mix of whatever colors you like. I personally love the flavor of red peppers, but wanted to give an ode to traditional stuffed peppers, so added a few green peppers.
- Beef: Lean ground beef makes this a lightened up stuffed pepper casserole, but any ground beef works, or you could use ground turkey or chicken.
- Rice: For the rice, any kind of long grain white rice works, just do not use parboiled or instant rice as they will make the final casserole mushy.
- Stock: Everything cooks in beef stock, which adds soooo much flavor, and if you wanted to up the protein even more, you could use beef bone broth instead.
- Tomato Paste: I’m skipping canned tomato soup here in favor of a bit of tomato paste that adds a concentrated boost of tomato flavor, but what do you do with the extras? It actually freezes really well for future recipes, or you can buy tomato paste in tubes which lasts a bit longer.
- Cheese: Last, but not least, the cheese! I used cheddar, but really any shredded cheese works (even dairy-free)! Or, you can skip the cheese for dairy-free.


Stuffed Pepper Casserole (Easy, One-Pot, w/ Rice!)
Ingredients
- 2 teaspoons extra virgin olive oil, divided
- 1 medium yellow onion, small diced
- 2 green bell peppers, small diced
- 2 red bell peppers, small diced
- 1 teaspoon kosher salt, divided
- 1 pound lean ground beef
- 4 garlic cloves, minced
- 2 tablespoons tomato paste
- 1 teaspoon smoked paprika powder
- 1 ½ cups beef stock
- 2 teaspoons Worcestershire sauce (see note)
- ¾ cup long-grain white rice
- ¾ cup shredded cheese of choice
Equipment
Instructions
- In a large (5- or 6-quart) pot or Dutch oven with a tight fitting lid, heat 1 teaspoon of the olive oil over medium-high heat. Add the onion and bell pepper, sprinkle with ¼ of the teaspoon salt, and cook until just beginning to soften, about 3-4 minutes, stirring occasionally.
- Add the remaining 1 teaspoon of olive oil, ground beef, and ¼ teaspoon of salt, and stir to break into small pieces. Cook until browned and just cooked through, about 5 minutes, stirring occasionally.
- Add the garlic, tomato paste, and smoked paprika. Cook until fragrant, about 1 minute, stirring constantly.
- Add the stock and Worcestershire sauce, and bring to a rapid boil. Add the rice and remaining ½ teaspoon of salt, stirring to combine.
- Cover, reduce to a low simmer, and cook for 15-18 minutes, or until the rice is just tender.
- Remove the pot from the heat, fluff the rice, and sprinkle the top with cheese. Allow to sit, covered, for an additional 5-7 minutes or until the rice is tender. Sprinkle with chopped parsley, if using, and serve.
Notes
- Make sure to use a large pot with tight fitting lid for the rice to cook properly.
- Be sure to use long grained rice (not instant or par-boiled) for best results.
- To make this casserole gluten free, use gluten free Worcestershire sauce.
- Check out the comments for serving suggestions – lots of readers recommend serving topped with sour cream and I concur!




Even though it’s Sept and still in the 90’s in TX…uggghh, I had to make this and it did not disappoint!! Used the food processer to chop the onion and peppers to make it easier. We also added a dollop of sour cream to our bowls, perfect compliment. I doubled the recipe and have a very small amount of leftovers so that says a lot 🙂
Angie, so happy you enjoyed even though the weather is not cooperating with us when it comes to casserole vibes! Great idea to serve with sour cream — I’ll definitely try that next time I make this. Thanks so much for leaving a reivvew!
Absolutely loved this one. I initially wondered if it would be flavorful enough for me due to the limited ingredients list, but it was truly so tasty and super simple. Another easy one heading into my rotation! I’ll probably prep the veggies a bit ahead next time to make it even quicker.
Jenny, so happy to hear this one was flavorful enough for you even with minimal ingredients — I do try to keep ingredient lists short without sacrificing on taste when I can! 🙂 Thanks so much for taking the time to leave a review!
This recipe is 3 generations approved!! I made it, my parents made it, and we just made for my grandparents. This will be a repeat for all of us! Thanks for creating an easy complete meal for this fall & winter.
Christina, 3 generations approved — what a major compliment! You definitely put a huge smile on my face. 🙂 Thanks so much for taking the time to leave a review, and I’m so happy to hear this one was a hit!
The comment to add the sour cream was …. GAME CHANGER! It was so good! We’ll definitely be making again.
Alyssa, okay, I’m convinced and will definitely have this with sour cream next time I make it, and will add a note to the recipe card as well. Thanks for the tip and for leaving a review!
Made this twice in two weeks! Added a can of black beans for more fiber and it was a perfect one-pot meal. Thanks for sharing!
Anna, so happy to hear this one is a hit, and I love the idea of adding a can of beans, so smart! Thanks so much for sharing that tip and for leaving a reivew!
Non-bell pepper lovers approved! I did not tell them there was bell pepper in it, and it was diced up pretty fine. Everybody loved it and said it’s definitely a keeper. So easy and delicious.
Melody, yay, I love to hear this one was a hit even with those who don’t love bell peppers! Thanks for your notes and for leaving a reivew!
This is SO delicious! I love how healthy it is with all the veggies and protein and how easy it is to make! One pot meals are the best for minimal cleanup. I really appreciate how you make recipes that are all the things I want as a busy mom-easy, healthy, and delicious!
Dana, yay, so happy to hear the recipes are helpful to you as a busy mama! Happy to hear you enjoyed this one, and thanks so much for taking the time to leave a review. 🙂
My family only uses 3 peppers. They like it better that way. I cook it for a few minutes longer to cook the moisture off but not much more than that.
The men who are not veggie eaters, will eat two servings and still ask for more. They ask for this 2 or 3 times a month.
Kathryn, fantastic to hear this one is a hit even with the men who don’t love veggies. Thanks for sharing your tips and for leaving a review!
This was exceptional. Easy and full of flavor. Will definitely be made again.
David, fantastic to hear this one was a hit and is worthy of the “make again” list! Thanks for sharing your thoughts and for leaving a reivew!
Why isn’t there any tomato sauce?
Hi Jackie, I’m not sure I understand your question. Are you asking why there isn’t tomato sauce in this recipe because you’re used to tomato sauce in stuffed peppers? I used tomato paste and spices here to add flavor rather than tomato sauce. I hope that answers your question!
Hi Robyn. Yes that does answer my question. Ty for getting back to me so quickly.
You’re so welcome, Jackie, I hope you enjoy!
I really appreciated finding your recipe and your take on a classic. Of course, I altered things because I didn’t have everything-used tomato sauce since I didn’t have paste, red onion since I only had half a yellow onion (and I love a lot of onions). More garlic, and I cooked the rice separately while sautéing the veggies and meat. Mixed it all up in a large cast iron skillet and baked for 15 min. This recipe is versatile and ideal for a large family meal that guarantees leftovers!
Debbie, I’m so happy to hear you enjoyed this stuffed pepper casserole and thanks so much for sharing your tips and notes!
I made this tonight and love it! I made the rice in my rice cooker yesterday for something else, and had enough to add to this. I had a small jar of fire roasted red peppers and added that as well as the other peppers, yum!
Jerrilynn, ohhhhh, roasted red peppers sound great in this one! So happy to hear you enjoyed – thanks so much for your tips and for leaving a review!
Hello,
I bought long grain jasmine rice instead. Will that be okay?
Thank you.
Hi Shea, yes, I’ve tested this recipe with jasmine rice and it works well. I hope you enjoy!
Great! Thank you.
You’re so welcome, Shea, enjoy!
Can I use leftover cooked rice?
Hi Julie, I haven’t tested this one with cooked rice, so I can’t say for sure. You’d definitely need to reduce the cook time and the liquid (stock) since those are both given for uncooked rice. If you give it a try let me know how it turns out!
Delicious! Tasteful and quick recipe!!
Teenage daughter even loved it!!
We doubled up recipe and used instant rice.
Sally, yay, so happy to hear this one was a hit with everyone. And good tip on the instant rice as well – did you reduce the cook time? I’m sure other readers would love to know. Thanks for sharing your notes and for leaving a review!
Delicious! Tasteful and quick recipe!!
Teenage daughter even loved it!!
We doubled up recipe and used instant rice. I did not reduce the cook time even with using the instant rice. I just kept the close eye on it..
Sally, fantastic! Happy to hear it was a with everyone, including the teen! Thanks for sharing your thoughts and for leaving a review. 🙂
So much easier than stuffing individual peppers. Great gluten-free meal, I left the meat out to make a vegetarian, and very satisfying.
Stacey, yay for easy recipes! Thanks for your tips on making this meal vegetarian, and for leaving a review!
Top with some crumbled goat cheese. Delicious!
Susan, ohhh, great idea! Thanks for sharing your thoughts and for leaving a review!
quick, easy with simple ingredients, family loves it.
Fantastic, Alora, I’m so happy to hear this one was a hit with the whole family! Thanks so much for sharing your thoughts and leaving a review!
This is always a hit with the kids, I tend to use red, yellow, and orange peppers but it just depends on what I have!
Jordan, yes, this one is so flexible and I love that you’re using what you have on hand. So happy to hear you’re enjoying this easy dinner – thank so much for sharing your thoughts and for leaving a review!
Hi! Would brown rice work as a swap for the white rice in this recipe?
Becca, yes, as long as it’s cooked first (as with the white rice) brown will work wonderfully in this recipe. I hope you enjoy!
Would cauliflower rice work in this as a substitute?
Not exactly. The recipe is written for a liquid ratio using rice, so if swapping if cauliflower you’d need to tinker with the recipe (both the amount of liquid and cooking time and method) quite a bit. If you feel like experimenting and give it a try, let me know how it turns out!
Could I use quinoa instead of rice?
Samantha, I haven’t tested it, so I can’t say for sure, but I think it would be fine! The liquid to quinoa ratio is the same as liquid to rice, so I don’t think you’ll need to change anything about the ingredient list, and I think the cook time should be about the same as well. If you give it a try let me know how it turns out!
