Stuffed banana peppers are a beloved comfort food, combining tender peppers with a savory filling and a zesty tomato sauce. Making them in the crock pot transforms this classic dish into a hands-off, fuss-free meal—perfect for busy weeknights or casual gatherings. Let your slow cooker do the work, and come home to a delicious, hearty dinner that tastes like it simmered all day.
Ingredients
- 8 medium banana peppers (about 1.5 pounds)
- 1 pound ground beef (or Italian sausage, or half of each)
- 1 cup cooked white rice
- 1/2 cup finely chopped onion
- 2 cloves garlic, minced
- 1/2 cup grated Parmesan cheese
- 1 large egg
- 1 teaspoon dried Italian seasoning
- 1/2 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 2 cups marinara sauce (homemade or store-bought)
- 1/2 cup shredded mozzarella cheese
- 2 tablespoons chopped fresh parsley (optional, for garnish)
- Olive oil spray (for greasing the crock pot)
Instructions
- Prepare the peppers: Slice off the stem ends of the banana peppers. Use a small knife or a spoon handle to carefully remove the seeds and membranes inside each pepper. Rinse and pat dry. If your peppers are very curved, you can slit one side lengthwise to help with stuffing.
- Mix the filling: In a large bowl, combine the ground beef (or sausage), cooked rice, chopped onion, minced garlic, Parmesan cheese, egg, Italian seasoning, salt, and black pepper. Use clean hands or a sturdy spoon to mix until evenly combined, but do not overwork the meat.
- Stuff the peppers: Gently fill each banana pepper with the meat mixture, pressing it in with your fingers or a small spoon. Leave a little space at the open end to prevent the filling from spilling out as it cooks.
- Layer in the crock pot: Lightly spray the inside of your crock pot with olive oil. Pour 1 cup of marinara sauce into the bottom. Arrange the stuffed peppers in a single layer (or two layers if needed), nestling them into the sauce. Spoon the remaining marinara sauce over the peppers.
- Cook: Cover and cook on LOW for 5 to 6 hours, or until the peppers are fork-tender and the filling reaches an internal temperature of 160°F (per USDA guidelines for ground beef). Avoid opening the lid during the first 4 hours to maintain an even temperature.
- Add cheese: About 15 minutes before serving, sprinkle the shredded mozzarella over the peppers. Cover and let it melt.
- Serve: Carefully remove the stuffed peppers with a spatula or tongs. Spoon extra sauce from the crock pot over each serving. Garnish with chopped parsley if desired.
Tips
- Substitutions: Swap the ground beef for ground turkey or a plant-based meat substitute for a lighter or vegetarian version. You can use brown rice, quinoa, or even cauliflower rice for a lower-carb filling.
- Make ahead: Stuff the peppers up to 24 hours in advance and refrigerate. In the morning, simply assemble in the crock pot and start cooking.
- Peppers too spicy? Banana peppers are generally mild, but if you prefer even less heat, soak them in cold water for 30 minutes after seeding.
- Don’t overstuff: Filling the peppers too tightly can make them burst or cook unevenly. Gently pack the filling and leave a little room at the ends.
Serving Suggestions
Stuffed banana peppers are delicious as a main dish or as part of a larger spread. Serve them over a bed of steamed rice or pasta to soak up the extra sauce. A simple green salad with vinaigrette and a slice of crusty Italian bread round out the meal perfectly. For a heartier dinner, pair with roasted vegetables or garlic bread. They also make a flavorful appetizer for parties—simply cut each pepper into halves or thirds before serving.
Variations
- Cheese lovers: Add cubes of mozzarella or provolone inside each pepper along with the filling for gooey, cheesy centers.
- Spicy kick: Mix in chopped jalapeños or a pinch of crushed red pepper flakes to the filling for more heat.
- Vegetarian version: Use a mixture of cooked lentils, sautéed mushrooms, and extra rice or quinoa instead of meat. Add chopped spinach for extra nutrition.
- Greek-style: Swap the Italian seasoning for oregano and dill, use feta instead of Parmesan, and serve with tzatziki sauce.
- Tex-Mex: Replace marinara with enchilada sauce and use cheddar or pepper jack cheese. Add black beans or corn to the filling.
Storage and Reheating
Let the stuffed banana peppers cool to room temperature before storing. Place leftovers in an airtight container and refrigerate for up to 4 days. For longer storage, freeze individual peppers (wrapped tightly and placed in a freezer-safe bag) for up to 2 months.
To reheat, place refrigerated peppers in a microwave-safe dish, cover, and heat on medium power for 2-3 minutes per pepper, or until hot. For best texture, reheat in a covered oven-safe dish at 350°F for 15-20 minutes. If frozen, thaw overnight in the refrigerator before reheating. Always check that the filling is hot all the way through before serving.
Frequently Asked Questions
- Can I use uncooked rice in the filling?
- It’s best to use cooked rice, as uncooked rice may not soften fully in the crock pot and can absorb too much liquid, leaving the filling dry. If you want to use uncooked rice, add extra sauce (about 1/2 cup) and expect a firmer texture, but pre-cooked rice is most reliable.
- Do I need to brown the meat before stuffing?
- No, you do not need to brown the meat. The slow cooker cooks the filling thoroughly and evenly. However, if you prefer extra flavor or want to reduce fat, you can brown and drain the meat first before mixing with the other filling ingredients.
- Can I cook on high to save time?
- While you can cook on HIGH for 2.5 to 3 hours, the peppers may be softer and the filling less juicy than when cooked on LOW. For best results and flavor, use the LOW setting. If short on time, check for doneness after 2.5 hours on HIGH.
- What type of banana peppers should I use?
- Look for firm, medium-sized yellow banana peppers without soft spots or blemishes. Mild banana peppers are traditional, but you can use Hungarian wax peppers for more heat, or substitute large sweet peppers if banana peppers aren’t available.
- Can I prepare this as a freezer meal?
- Yes! Assemble and stuff the peppers, then freeze them (uncooked) in a single layer on a baking sheet. Once frozen, transfer to a freezer bag. Thaw overnight in the refrigerator before placing in the crock pot with sauce and cooking as directed.
- How do I keep the peppers from falling apart?
- Don’t overfill the peppers, and try to keep them in a single layer or gently stacked in the crock pot. Using peppers that aren’t overripe or too thin-walled also helps them hold their shape during the long, slow cook.
