Ingredients for Vegetarian Stuffed Peppers

• Brown rice: Wholesome, fiber-rich brown rice is the grain base for these vegetarian stuffed bell peppers. Cook brown rice on the stovetop and allow it to cool slightly before mixing it with the remaining filling ingredients.
• Vegetables: Chopped tomatoes, frozen corn and sweet onions add character to the stuffed pepper filling.
• Cheese: Melty, mild Monterey Jack cheese adds gooey richness to the peppers, while Parmesan cheese imparts a deep, savory flavor.
• Beans: For protein, the vegetarian stuffed peppers recipe includes canned black beans and red beans.
• Aromatics: Stir minced garlic cloves, fresh basil and chopped olives into the rice filling. Use whichever type of olive you like.
• Seasonings: Keep it mild with simple salt and pepper.
• Sweet peppers: The best type of pepper for stuffed peppers is wide and symmetrical, with ample room for stuffing. Choose large sweet peppers in whichever color you like for this vegetarian stuffed peppers recipe.
• Meatless spaghetti sauce: Pick up the best jarred tomato sauce at the store or use a homemade simple pasta sauce in this recipe. Either way, dilute the sauce with a bit of water so there’s enough liquid in the slow cooker to cook the peppers.

How to Make Stuffed Peppers in the Oven

To make baked stuffed peppers, preheat the oven to 350°F. Fill the peppers as directed. Prepare the sauce and pour half the mixture into an ungreased 3-quart baking dish. Add the stuffed peppers and top with the remaining sauce. Sprinkle with cheese as directed.

Bake, covered, for 30 to 35 minutes or until the filling is heated through and the peppers are tender.

Recipe Variations

• Spice it up: The filling’s flavor can be adjusted by adding spices or herbs. Go herbal with dried Italian seasoning, add fresh parsley and chives, spice it up with cayenne and paprika, or make Mexican-inspired peppers by adding cumin and homemade taco seasoning.
• Switch the beans: Most types of beans work here, so feel free to swap in white beans, chickpeas or lentils. You can use just one or mix and match.
• Change the veggies: Go ahead and play with the vegetables in the filling. Add mushrooms, asparagus, broccoli, cauliflower, carrots, tomatoes—whatever you like. Just make sure to chop them into small, uniform bites, and avoid using veggies like beets or winter squash that are too firm to cook in the allotted time.
