Ingredients You’ll Need

The beauty of this Stuffed Pepper Casserole is that every ingredient is both simple and essential—their harmony gives you maximum flavor with minimal effort. Each one brings its own magic, whether it’s color, heartiness, or that irresistible cheesy finish!

• Olive oil: This brings a subtle richness that helps everything sauté to tender perfection.
• Lean ground beef: The main source of hearty protein and classic stuffed pepper flavor (but you can totally sub ground turkey or chicken if you like!).
• Yellow onion: Softens beautifully into the background, adding sweetness and depth to the casserole.
• Red and green bell peppers: Diced, these bring gorgeous color and signature sweet-tangy pepper flavor to every spoonful.
• Garlic: Three petite cloves, minced, add that irresistible savoriness you crave in homey casseroles.
• Italian seasoning or Cajun seasoning: Your choice! Italian for herby goodness or Cajun for a little kick.
• Worcestershire sauce: This tiny splash is my favorite secret—umami flavor that makes the dish taste “complete.”
• Salt and pepper: Just the right amount to make every flavor shine.
• Canned diced tomatoes: Adds juicy texture and brings all the savory, tangy notes you expect.
• Long grain white rice: Absorbs all that delicious flavor and gives perfect, fluffy texture.
• Beef broth: Makes the rice ultra savory and keeps every bite moist (never mushy!).
• Shredded cheese: A blend of cheddar and mozzarella melts into a bubbly, golden topping you’ll want on every casserole.
• Fresh parsley: For a bright, fresh garnish just before serving!

Variations

The best thing about Stuffed Pepper Casserole is how customizable it is! Don’t be afraid to swap ingredients or add your own favorite flavors—the recipe is forgiving and perfect for adapting to your cravings or dietary needs.

• Make it Vegetarian: Swap the beef for cooked lentils or a meatless ground—it’s still hearty and delicious!
• Keto or Low-Carb: Replace rice with cauliflower rice and cut the baking time by 5-10 minutes for a satisfying, low-carb dinner.
• Add Extra Veggies: Toss in mushrooms, zucchini, or even a handful of baby spinach for extra color and nutrition.
• Spicy Twist: Use pepper jack cheese and add a pinch of red chili flakes or diced jalapeños if you like a little heat!

How to Make Stuffed Pepper Casserole

Step 1: Brown the Beef

Preheat your oven to 350°F (180°C). In a large, oven-safe skillet or casserole dish, warm the olive oil over medium-high heat. Add the ground beef, breaking it up with a spatula, and cook until it’s browned and no longer pink, about 5-6 minutes. Don’t forget to drain off any excess fat for a lighter casserole.

Step 2: Sauté the Veggies

Stir in the diced onion and bell peppers. Let them cook for 2-3 minutes, just until they start to soften and your kitchen smells like comfort food magic. You want the veggies to be tender but still vibrant for the best texture.

Step 3: Add Flavor

Next, toss in your minced garlic, seasoning, Worcestershire sauce, salt, and pepper. Stir and cook for about 30 seconds until everything is fragrant—there’s nothing better than the aroma of garlic mingling with spices.

Step 4: Bring on the Tomatoes and Rice

Pour in the diced tomatoes (juice and all) and stir to combine. Then add the uncooked rice and beef broth, giving everything another good mix to be sure the rice is evenly distributed.

Step 5: Bake Until Perfect

Cover your skillet or casserole with a fitted lid or foil and transfer it to the oven. Bake for 20-25 minutes, then peek and test a little rice. If it’s tender and fluffy, you’re golden! If it needs a bit more time or moisture, add a splash of water and bake for a few more minutes.

Step 6: Finish with Cheese and Broil

Sprinkle the shredded cheese over the bubbly casserole and pop it under the broiler for 3-5 minutes. Watch carefully—you’re aiming for golden, melty bliss! Shower with fresh parsley and serve piping hot.

How to Serve Stuffed Pepper Casserole

Garnishes

For that restaurant-worthy finish, sprinkle plenty of fresh chopped parsley right before serving—its color pops beautifully against the cheesy top! If you like a little kick, a pinch of red pepper flakes or a tiny drizzle of hot sauce takes it up a notch. Even a dollop of sour cream or a handful of sliced green onions is welcome here for extra creaminess and crunch.

Side Dishes

A crisp green salad with a lively vinaigrette is my favorite match—its freshness balances out the richness of the casserole. You also can’t go wrong with crusty bread to mop up the saucy, cheesy bits, or a simple bowl of steamed green beans for something light but satisfying alongside your Stuffed Pepper Casserole.

Creative Ways to Present

Try spooning the Stuffed Pepper Casserole into hollowed roasted peppers for a stunning dinner party twist. Or, bake individual portions in ramekins for a cozy, just-for-you feel! For family potlucks or game nights, serve it family-style in the baking dish and let everyone dig in together—there’s something magically comforting about this interactive experience.

Make Ahead and Storage

Storing Leftovers

Let the remaining casserole cool completely, then cover tightly or place in airtight containers. It will stay fresh in the fridge for up to 4 days, and actually tastes even better the next day as the flavors mingle.

Freezing

Stuffed Pepper Casserole freezes beautifully! After cooling, freeze individual portions or the whole casserole tightly wrapped. It keeps well for up to 2–3 months. Thaw overnight in the fridge before reheating for best results.

Reheating

To reheat, cover leftovers and warm in a 350°F oven for about 20 minutes or until hot through (add a splash of broth if it seems dry). For a quick lunch, microwave individual servings in 45-second intervals, stirring in between for even heating. Add a little fresh cheese or parsley to revive it!
