Stuffed bell peppers are one of those classic comfort meals. They are simple, filling, and easy to change up. This crockpot version makes it even easier by letting the slow cooker do all the work. You get tender peppers, flavorful beef, and cheesy goodness all in one tidy package, without needing to turn on the oven.

Jump to Recipe

With just a handful of ingredients, this recipe comes together fast. The beef, rice, tomatoes, and seasoning form a savory filling that stays juicy as it cooks. A bit of cheese inside the filling adds richness, and a sprinkle on top right before serving brings it all together.

It’s a great dinner option when you want something warm and satisfying but don’t need a big batch. And because it’s scaled for two, there’s no waste and no crowding your slow cooker.

Why These Crockpot Stuffed Bell Peppers Work

The filling goes into the peppers raw. That sounds odd at first, but it is the reason this recipe works so well in a slow cooker. As the beef cooks low and slow inside the pepper, its juices soak into the rice and tomatoes instead of ending up in a skillet you have to drain. The rice picks up all that flavor, and the meat stays moist instead of turning dry and crumbly.

The peppers also act like little steamers. Standing upright in a small crockpot, they soften over 5 to 6 hours until a fork slides in easily, but they still hold their shape. A small 3 to 4 quart cooker matters here. In a big 6 quart model, two peppers tend to tip over and the bottoms can scorch.

Ingredients and Easy Swaps

Bell peppers: Pick two wide peppers with flat bottoms so they stand up on their own. Red, yellow, and orange peppers taste sweeter after cooking. Green peppers are a little more bitter and stay slightly firmer.

Ground beef: Half a pound fills two medium peppers. An 85/15 blend keeps the filling juicy. Ground turkey works too, but add a pinch more salt and seasoning since it is milder, and cook it to 165°F.

Cooked rice: Use leftover white or brown rice, or half of a microwave rice pouch. Do not use uncooked rice. There is not enough liquid in the peppers for it to soften. Cooked quinoa is an easy swap.

Tomatoes and seasoning: A couple tablespoons of canned diced tomatoes with their juice keep the filling moist. Italian seasoning gives you basil, oregano, and thyme in one jar. If you don’t have it, use 1/4 teaspoon each of dried oregano and dried basil.

Cheese: Cheddar, mozzarella, or a Mexican blend all melt well. A little goes inside the filling, and the rest goes on top at the end.

How to Make It at a Glance

1. Cut the tops off the peppers and pull out the seeds and white ribs.
2. Mix the raw ground beef, cooked rice, diced tomatoes, 1 tablespoon of cheese, Italian seasoning, salt, and pepper in a bowl.
3. Spoon the filling into the peppers and stand them upright in a 3 to 4 quart slow cooker.
4. Cover and cook on low for 5 to 6 hours, until the beef reaches 160°F and the peppers are tender.
5. Sprinkle more cheese on top, cover for a few minutes to melt it, and serve.

Common Mistakes to Avoid

Packing the filling too tight. Press it in gently. Tightly packed beef turns dense, and the center takes longer to cook through.

Skipping the thermometer. Ground beef needs to reach 160°F in the center. The peppers can look done before the middle of the filling is ready, so check the thickest part.

Lifting the lid. Every peek lets heat escape and can add 15 to 20 minutes to the cook time. Wait until at least the 5 hour mark to check.

Using a slow cooker that is too big. Two peppers in a large crock fall over and cook unevenly. If a big one is all you have, wedge a ball of foil between the peppers to keep them upright.

Variations

Tex-Mex peppers: Swap the Italian seasoning for 1 teaspoon of taco seasoning, use pepper jack cheese, and stir a spoonful of black beans into the filling.

Sausage and beef: Use half ground beef and half mild Italian sausage. Top with mozzarella and a spoonful of warm marinara at the end.

Lower carb: Use 1/4 cup of riced cauliflower in place of the rice. It cooks down a bit, so the filling will be softer.

Extra veggies: Chop the pepper tops you cut off, toss the stems, and mix the pieces into the filling with a little diced onion.

What to Serve With It

Serve your stuffed peppers with:

• Roasted potatoes or garlic bread, great for soaking up the juices
• A simple green salad with a sharp vinaigrette for something crunchy
• Steamed green beans or zucchini to keep the plate fresh and colorful

For a little heat, try adding red pepper flakes or swapping in pepper jack cheese. These also reheat well if you want to make them ahead.

Make Ahead, Storage, and Reheating

You can stuff the peppers up to 24 hours ahead. Cover them tightly and keep them in the fridge, then set them in the slow cooker when you are ready to start. They may need an extra 20 to 30 minutes since they start out cold, so go by the thermometer, not the clock.

Cooked peppers keep in an airtight container in the fridge for 3 to 4 days. To freeze, let them cool, wrap each one in plastic wrap, and put them in a freezer bag. They keep for up to 3 months. Thaw them overnight in the fridge.

To reheat, put a pepper in a covered microwave-safe dish and heat for 2 to 3 minutes, until it is hot in the center. You can also bake them covered at 350°F for 20 to 25 minutes. Add fresh cheese after reheating so it melts nicely.

Frequently Asked Questions

Do I need to brown the ground beef first?
No. The raw beef cooks right inside the peppers. Just make sure the center of the filling reaches 160°F before you serve it.

Can I cook these on high?
Yes. Cook on high for about 3 hours. Low is gentler, so the peppers hold their shape better, but high works when you start later in the day.

Should I add water to the slow cooker?
You don’t need to. The peppers and tomatoes give off enough moisture. If your slow cooker runs hot, add 2 to 3 tablespoons of water or broth to the bottom of the crock.

Can I double this recipe?
Yes. Double everything and use a 5 to 6 quart slow cooker so all four peppers fit standing up. The cook time stays about the same.

These Crockpot Stuffed Peppers are the ideal slow cooker dinner for two, with no baking required. Each bell pepper is filled with a flavorful mix of seasoned ground beef, rice, and tomatoes, then cooked until perfectly tender.

It’s a complete meal in an edible bowl with no waste and no reheating tomorrow.
