Roasted Red Pepper Tomato Soup (Canned Tomatoes)
Made with canned tomatoes, jarred roasted red peppers, and a handful of pantry seasonings, this roasted red pepper and tomato soup tastes restaurant-worthy with almost no effort! It blends up creamy and smooth in under 30-minutes on the stovetop, with slow cooker instructions included for a hands-off option.

Easy Tomato and Red Pepper Soup in the Slow Cooker or Stovetop!
Okay, real talk, I always keep the ingredients for this roasted red pepper and tomato soup on hand, because it’s the kind of cozy, restaurant-worthy meal I can pull together on the busiest weeknight. The secret? Using canned fire-roasted tomatoes and jarred roasted red peppers, which means you skip the roasting entirely but still get all that deep, smoky-sweet flavor. Blended smooth with a touch of cream at the end, it tastes like something you’d order out, and decidedly not something that came from your pantry in under 30-minutes!
A couple of notes from testing that I want to pass along. First, don’t skip the quick sauté of the onion, garlic, and tomato paste at the start, because those few extra minutes create the savory depth that makes the soup taste slow-simmered rather than thrown together. Second, the brown sugar at the end makes a difference, and not just adding sweetness. A small spoonful balances the natural acidity of the tomatoes and peppers and rounds the whole thing out, so taste before you decide to leave it out.
And that texture is all in the blend! An immersion blender right in the pot is the easiest route, but a countertop blender will give you the silkiest, most velvety result if that’s what you’re after, just work in batches and vent the lid so steam can escape. This soup is made for dipping, so serve it with a few thick slices of my garlic bread for a cozy soup night. And if you have half a jar of roasted red peppers left over, my butternut squash and red pepper soup puts them to good use!

Robyn’s Testing Tips for Creamy Roasted Red Pepper Soup
- Reach for canned fire-roasted diced tomatoes over regular diced; they add a layer of smoky depth with no extra effort!
- Make it dairy-free and vegan by swapping the heavy cream for unsweetened non-dairy creamer and the butter for a plant-based version.
- If you have homemade roasted peppers on hand, substitute about 3 medium peppers for the 16-ounce jar.
- This soup tastes even better the next day and freezes well for up to 2 to 3 months, so make a double batch and stash half for a future easy dinner!

So easy to make! Loving that the roasted pepper add a lot of flavor and take away some of the tomato’s acidity. This is my new go to soup recipe.
