Stuffed Bell Peppers

Method

1. Make the filling by browning the ground beef with diced onion in a large skillet over medium-high heat for 5 minutes. Add garlic and Italian seasoning, cook 1 minute. Add diced tomatoes and cooked rice. Stir to combine and season with salt and pepper. The filling should be moist but not soupy.

2. Stuff each pepper generously with the filling, pressing it down gently. Stand the peppers upright in a baking dish that holds them snugly. Top each with shredded mozzarella.

3. Cover tightly with foil and bake at 375°F for 30 minutes. The foil traps steam, which softens the peppers from the outside while the filling heats through. Without the foil, the cheese burns before the peppers are tender.

4. Remove the foil and bake 10 minutes more until the cheese is melted, bubbly, and golden in spots. The peppers should be soft but still holding their shape.

5. Rest for 5 minutes before serving. Garnish with fresh basil or parsley. The filling is molten hot and needs a moment to set.

Equipment

• Large skillet Recommended: Joyce Chen 14-Inch Carbon Steel Wok
• 9x9 or 8x8 baking dish
• Aluminum foil

Chef Notes

• The most important thing: Par-cook the filling on the stovetop before stuffing. The peppers only need 30–40 minutes in the oven to soften — not enough time to cook raw beef and rice from scratch. Pre-cooking the filling means everything finishes at the same time.
• Cover with foil for the first 30 minutes to steam the peppers tender, then uncover for the last 10 to melt and brown the cheese.
• Stand the peppers upright in a baking dish that fits them snugly. They support each other and stay upright during baking.
• Use any color bell pepper. Red and yellow are sweeter; green is more vegetal and slightly bitter. Mix them for visual variety.
• The diced tomatoes in the filling provide moisture that keeps the rice from drying out during baking.

Common Substitutions

Ingredient	Substitution	Notes
Ground beef	Ground turkey or plant-based ground	Turkey is leaner — add 1 tbsp oil. Plant-based works for texture.
Mozzarella	Provolone or vegan mozzarella	Provolone melts well with more flavor.
Canned tomatoes	Fresh tomatoes (blanched, peeled) or passata	1 lb fresh = one 14 oz can. Passata is smoother.
Fresh garlic	Garlic powder (¼ tsp per clove)	Fresh is always better but powder works in a pinch.
Fresh basil	Thai basil or dried basil (1 tsp per tbsp fresh)	Thai basil is spicier. Dried works in cooked dishes only.

What You're Practicing

Stuffed peppers teach you about assembled baked dishes — pre-cooking components separately, then combining and finishing in the oven. This same approach applies to stuffed mushrooms, stuffed zucchini, and any dish where a vessel is filled with a cooked filling. Visit Techniques for more on assembled baking.

Using foil to control moisture during baking is a technique that applies to enchiladas, lasagna, and any baked dish where you need to balance tender interiors with browned tops. Covered baking steams; uncovered baking browns. Combining both gives you the best of both worlds.
