Gather Your Ingredients: Start by brown the ground beef in a skillet and chop the onion, garlic, and bell peppers to prepare.
Combine Everything in the Slow Cooker: Pour the cooked beef and the diced vegetables into the slow cooker. Add in the fire-roasted diced tomatoes, tomato sauce, chicken broth, oregano, basil, salt, and black pepper.
Stir Well: Mix all the ingredients to ensure even distribution of flavors.
Let It Cook: Cover and cook on HIGH for 4 hours or LOW for 8 hours. Remember, refrain from opening the lid during the cooking time to keep the heat contained.

Plan Ahead

To make busy days easier, you can prep ingredients a day or two ahead of time. Chop the onions and peppers, and store them in an airtight container in the refrigerator. You can also brown the ground beef and store it, so when it’s time to cook, everything is ready to add to your slow cooker. Just remember to store the rice separately until you’re ready to add it in.

How to Store Leftovers

If you happen to have leftovers—which is unlikely with such a delicious soup—you can store them in the refrigerator for up to 3 days. For longer storage, portion the soup into airtight containers and freeze for up to 3 months. To reheat, simply thaw and warm gently on the stove or in the microwave until heated through. The soup will retain its delicious flavor, but if you notice it has thickened too much, add a splash of chicken broth to loosen it up.

Perfect Pairings

Slow Cooker Stuffed Pepper Soup is a complete meal on its own, but these sides complement it beautifully:

A warm baguette or country loaf for dipping.
A fresh garden salad to add crunch and freshness.
Cornbread for a sweet companion to the savory soup.
Homemade garlic knots for an extra layer of comfort alongside your soup
A light avocado and citrus salad for a refreshing contrast.

Flavor Twists and Substitutions

Feel free to personalize this soup to suit your taste! Here are a few variations:

Substitute ground turkey or ground chicken for a lighter option.
Add in other colorful bell peppers like yellow or orange for a sweeter taste.
Include kidney or black beans for added protein.
Toss in some corn for sweetness and texture.
If you like spice, consider adding diced jalapeños or a splash of hot sauce.
Fresh herbs like parsley or cilantro can add a lovely herbal brightness just before serving.

Cook’s Notes and Secrets

To achieve the best results with your Slow Cooker Stuffed Pepper Soup, consider these tips:

Browning the beef enhances its depth of flavor before it’s added to the slow cooker.
Use fresh vegetables for the best taste; frozen will work, but fresh is preferable.
Avoid lifting the lid during cooking to maintain even heat and cooking time.
If using cooked rice, reduce the cooking time and add it at the end to warm through.

Your Questions Answered

Can I make this soup vegetarian? Absolutely! Replace the ground beef with lentils or a plant-based meat substitute and use vegetable broth.
Is the soup gluten-free? Yes, this recipe is naturally gluten-free, as long as you ensure all canned products do not contain gluten ingredients.
Can I use brown rice instead of Minute rice? Yes, but remember that brown rice requires a longer cooking time. You would need to add it earlier in the cooking process.
What can I add to spice it up? You can add chili powder, cayenne pepper, or diced jalapeños for a kick.
How do I know when it’s done? The soup should be bubbling and the rice fully cooked. Check for a tender texture throughout.
