How to Make Roasted Red Pepper and Tomato Soup
This flavorful soup comes together in simple steps. The full recipe with quantities and timing is included near the bottom.

- Step 1: Cut the red pepper in half and remove seeds, stem and membrane. Place cut-side down on a foil-lined baking sheet and roast until the skins are blackened and the pepper is soft.

- Step 2: Let the pepper cool, peel off and discard the skin, then coarsely chop and set aside.

- Step 3: In a large pot, melt butter over medium heat. Add chopped onion and garlic and cook until soft and translucent—avoid browning. Stir in flour and cook briefly to remove the raw taste.

- Step 4: Add the diced tomatoes with their juices, roasted red pepper, chicken stock, sugar, salt, red pepper flakes, and black pepper. Bring to a boil, then reduce to a low simmer.

- Step 5: Simmer for about 30 minutes to let flavors meld. Stir in honey, then remove from heat and allow the soup to cool slightly before blending.

- Step 6: Blend until smooth with an immersion blender or in batches in a countertop blender. Stir in milk to finish, then serve garnished with fresh basil.
Expert Cooking Tips
- Peeling the peppers: Roasted skins slip off easily once the peppers cool and deflate.
- Rough chop is fine: Since the soup is blended, you don’t need finely diced vegetables.
- Blending safely: Use an immersion blender or a countertop blender in batches. Let the soup cool slightly and blend carefully to avoid hot splashes.
- Finishing touches: Top with fresh basil and a sprinkle of salt and pepper for brightness.
Storage
Refrigerator: Cool completely, store in an airtight container for up to 4 days. Reheat gently on the stovetop or in short bursts in the microwave.
Freezer: Cool fully, freeze in an airtight container for up to 3 months. Thaw overnight in the fridge before reheating.
