Ingredients for One-Pot Roasted Red Pepper and White Bean Soup

Instructions

Heat olive oil in a large, heavy-bottomed pot over medium heat.
Add diced onion and sauté until translucent and soft, about 5-6 minutes.
Stir in minced garlic and cook for 1 minute until fragrant.
Add chopped roasted red peppers, white beans, smoked paprika, cumin, and crushed red pepper flakes (if using). Stir well to combine.
Pour in the vegetable broth and bring mixture to a boil.
Reduce heat to low and simmer uncovered for 20 minutes to meld flavors.
Use an immersion blender to partially puree the soup in the pot, blending about half for a creamy yet textured soup. Alternatively, puree half the soup in a blender and return to pot.
Season with salt, freshly ground black pepper, and fresh lemon juice. Adjust seasoning to taste.
Ladle soup into bowls and garnish with chopped fresh parsley before serving.
For meal prep: cool completely, then store in airtight containers in the refrigerator up to 4 days or freeze for up to 3 months.
