• 1 Medium Yellow Onion: Finely chopped.
• 3 Cloves Garlic: Minced.
• 1 can (14 oz) Diced Tomatoes: With juices.
• 1/2 cup Tomato Sauce: For rich, moist stuffing.
• 1 tsp Italian Seasoning: Blend of oregano, basil, and rosemary.
• 1/2 tsp Smoked Paprika: Adds depth and subtle warmth.

Step-by-Step Instructions for Roasted Stuffed Bell Peppers

1. Preheat the Oven and Prep Peppers: Preheat your oven to 375°F (190°C). Slice the top half-inch off each bell pepper and remove the internal seeds and white membranes. Lightly brush the outsides with olive oil and place them standing upright in a deep baking dish.
2. Brown the Meat: Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the chopped onion and cook for 3 minutes until translucent. Add the ground beef and minced garlic, breaking up the meat with a wooden spoon until browned and fully cooked. Drain off any excess fat.
3. Mix the Filling: Stir the diced tomatoes, tomato sauce, cooked rice, Italian seasoning, smoked paprika, salt, and black pepper into the skillet. Simmer on low heat for 3–4 minutes until thoroughly combined and aromatic. Remove from heat and fold in 1/2 cup of shredded cheese.
4. Stuff the Peppers: Spoon the warm beef and rice mixture generously into each prepared pepper cavity, pressing down lightly until filled to the top rim.
5. Bake to Tender Perfection: Pour 1/4 cup of water into the bottom of the baking dish around the peppers to create gentle steam. Cover the dish tightly with aluminum foil and bake for 20 minutes until the peppers turn fork-tender.
6. Melt the Cheese: Remove the foil, sprinkle the remaining 1 cup of mozzarella cheese over the tops, and return to the oven uncovered for an additional 5 minutes until the cheese is melted and bubbling golden brown.
7. Garnish and Serve: Let the stuffed peppers rest for 5 minutes before serving. Garnish with chopped fresh parsley.

Chef’s Note: Par-baking the peppers covered with foil with a splash of water in the baking dish creates steam, ensuring the peppers soften completely without burning or drying out the beef filling.

Pro Tips for the Best Results

• Choose Flat-Bottom Peppers: When buying bell peppers at the grocery store, select ones with flat, stable bases so they stand upright easily in the baking dish without tipping over.
• Internal Pairing: Looking for more comforting skillet and oven meals? Pair this dinner with our tender Lobster Bisque with Saffron Infusion or creamy soup favorites!
• Safe Cooking Standards: Make sure cooked ground meat reaches a safe internal temperature of 160°F as specified by USDA Food Safety guidelines.

Storage and Meal Prep Instructions

• Refrigeration: Store leftover roasted stuffed bell peppers in an airtight glass container in the refrigerator for up to 3 to 4 days.
• Reheating: Reheat in a preheated oven at 350°F (175°C) for 10–12 minutes, or microwave for 1.5 to 2 minutes until heated through.
• Freezing: Assemble the stuffed peppers completely without baking, wrap each pepper tightly in plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking as directed.

Frequently Asked Questions About Roasted Stuffed Bell Peppers

Can I make vegetarian stuffed bell peppers?

Yes! Simply replace the ground beef with black beans, pinto beans, or cooked lentils, and add corn kernels or sautéed mushrooms for extra hearty texture.

Do I need to pre-cook the rice before stuffing?

Yes, the rice must be fully cooked beforehand. Uncooked rice will not soften properly during the 25-minute baking time and will absorb all moisture from the sauce.

Which bell pepper colors taste best for roasting?

Red, yellow, and orange bell peppers are naturally sweeter and develop rich caramelized flavor when roasted. Green bell peppers are slightly more bitter and herbal, but work well if you prefer a sharper taste.
