Ingredients You’ll Need

This recipe uses simple, everyday ingredients that come together beautifully to create layers of flavor and texture. Each item plays a key role: from the rich ground beef that adds heartiness to the bright bell peppers giving the soup its cheerful color and fresh bite. The tomato sauce and diced tomatoes bring tang and depth, while the rice adds a subtle chewiness that makes this dish truly satisfying.

1 teaspoon avocado oil: Use this for a subtle, healthy fat that helps brown the beef without overwhelming flavors.
1 lb. ground beef: Provides hearty protein and soaks up all the delicious spices and tomatoey juices.
2 green or red bell peppers, chopped: These add crunch, sweetness, and a beautiful color contrast.
1 onion, chopped: Essential for a savory base and aromatic foundation.
1 (15 oz.) can tomato sauce: Brings rich, smooth tomato flavor that makes the broth luscious.
1 (15 oz.) can diced tomatoes: Adds fresh, slightly chunky texture to complement the smooth sauce.
3 cups beef or chicken stock: The flavorful liquid backbone that tenderizes the rice and blends all ingredients.
1 tablespoon coconut sugar (optional): Balances the acidity for a subtle sweetness; can be omitted for Whole30.
1 teaspoon garlic powder: Gives that unmistakable savory punch without the fuss of fresh garlic.
1 teaspoon ground black pepper: For a touch of warmth and depth.
1 teaspoon fine sea salt: Enhances all the natural flavors throughout the soup.
1 teaspoon paprika: Adds a gentle smokiness to round out the taste profile.
1/4 cup white rice, uncooked: Hearty grains that absorb the flavorful broth and add substance.
Scallions, sliced: Fresh, zesty garnish that brightens every spoonful.
Cheddar cheese, shredded (optional): A melty, savory topping that turns every bite into comfort food heaven.

How to Make Slow Cooker Stuffed Pepper Soup Recipe

Step 1: Brown the Beef

Start by heating the avocado oil in a pan over medium heat or directly in your slow cooker insert if it’s safe to do so. Add the ground beef and cook it until it’s no longer pink, breaking it into small pieces as it browns. This step is crucial because it builds the base flavor and gives the soup that delicious meaty richness. Once browned, drain off most of the excess fat, leaving just a teaspoon to keep things moist and flavorful.

Step 2: Combine Ingredients in the Slow Cooker

Transfer your perfectly browned beef to the slow cooker. Now, add the chopped bell peppers and onion—they will soften and sweeten as they cook over time. Pour in the tomato sauce, diced tomatoes, and your choice of beef or chicken stock. Next, sprinkle in the coconut sugar if using, garlic powder, ground black pepper, fine sea salt, and paprika. Give everything a good stir to incorporate those gorgeous spices throughout the mixture.

Step 3: Add the Rice

Instead of stirring the rice into the soup mixture, sprinkle it evenly on top. This little detail helps the rice cook evenly in the steam that builds inside the slow cooker, preventing it from becoming mushy. It also allows you to monitor its cooking progress more easily by peeking through the lid when the time’s nearly up.

Step 4: Slow Cook to Perfection

Seal the slow cooker with its lid and set it to cook on high for about 4 to 6 hours. Around the 4-hour mark, check the rice for doneness—you’re looking for tender grains that have soaked up just enough broth without falling apart. This gentle cooking process melds all the savory flavors together beautifully and turns the dish into a soul-satisfying bowl of comfort.

Step 5: Season and Serve

Once the rice is cooked to perfection, give the soup a taste and tweak the seasonings if needed—maybe a pinch more salt or pepper depending on your preferences. Ladle the soup into bowls and garnish generously with sliced scallions for that fresh, green crunch. If you’re feeling indulgent, sprinkle shredded cheddar cheese on top so it melts luxuriously into the piping hot soup.

Garnishes

Adding bright scallions is a simple touch that really elevates the soup with a fresh oniony snap. For an extra layer of indulgence, melted cheddar cheese brings creamy richness that contrasts beautifully with the broth’s tart tomato base. A dollop of sour cream or a sprinkle of fresh herbs like parsley or cilantro can also add wonderful coolness and color.

Side Dishes

This soup is filling on its own, but pairing it with crusty bread or garlic toast makes for a delightful and complete meal. A crisp green salad with a light vinaigrette offers a refreshing counterpoint to the richness of the soup. For a heartier spread, roasted vegetables or a simple baked potato work wonders alongside the stew-like qualities of this dish.

Creative Ways to Present

If you’re serving this Slow Cooker Stuffed Pepper Soup Recipe at a casual dinner party, try offering toppings buffet style—cheddar cheese, scallions, sour cream, even some crushed tortilla chips for added texture. Alternatively, using colorful bowls that match the soup’s vibrant red and green hues can really make the meal feel festive and inviting.

Make Ahead and Storage

Storing Leftovers

Leftover Slow Cooker Stuffed Pepper Soup Recipe stores beautifully in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen as it sits, making it perfect for next-day lunches or easy dinners when you’re short on time but craving something hearty.

Freezing

You can freeze this soup in portions for up to 3 months. Be sure to cool it completely before transferring into freezer-safe containers or zip-top bags. Label them with the date so you can easily track freshness. When frozen, the rice may absorb some extra moisture, so you might want to add a splash of broth while reheating to restore the perfect consistency.

Reheating

Reheat the soup gently on the stovetop over low to medium heat, stirring occasionally. Adding a little extra broth or water helps loosen the texture if it has thickened too much. You can also warm it in the microwave in short bursts, stirring in between to heat evenly and maintain that comforting, homemade taste.

FAQs

Can I use a different type of meat in this Slow Cooker Stuffed Pepper Soup Recipe?

Absolutely! Ground turkey or chicken work well for a leaner version, though you may want to add a touch of olive oil to keep the dish moist and flavorful. You can also try a plant-based ground meat substitute if you prefer a vegetarian take.

Is there a way to make this soup Whole30 compliant?

Yes! Simply omit the coconut sugar and ensure your broth and canned tomatoes have no added sugars or preservatives. This will keep the soup hearty and flavorful while aligning with Whole30 guidelines.

Can I prepare this soup in an Instant Pot?

Definitely! Use the sauté function to brown the beef and soften the onions and peppers, then add all remaining ingredients except rice, which you should sprinkle on top. Cook on manual high pressure for about 10 minutes, letting the pressure release naturally for 5 minutes before releasing any remaining pressure.

What if I don’t have white rice on hand?

While white rice is recommended for cooking evenly in the slow cooker, you can also try brown rice, but it will require a longer cooking time and more liquid. Another option is to leave the rice out and serve the soup over cooked rice just before eating to maintain texture.

Can I make this soup spicier?

For sure! Add a pinch of red pepper flakes, a diced jalapeño with the bell peppers, or a splash of hot sauce to kick up the heat. Just be sure to adjust seasoning gradually to keep the balance of flavors right.
