Ingredients List
Transform your kitchen into a comfort food paradise with these carefully selected ingredients that create the perfect harmony of flavors:
For the Casserole Base:
- 1 pound lean ground beef (85/15 blend for optimal flavor)
- 4 large bell peppers (red, yellow, and green for vibrant color), diced
- 1 large yellow onion, finely chopped
- 3 cloves garlic, minced
- 1 cup long-grain white rice, uncooked
- 1 can (14.5 oz) diced tomatoes, drained
- 2 cups beef broth (low-sodium preferred)
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried oregano
- 1/2 teaspoon smoked paprika
- Salt and freshly ground black pepper to taste
For the Cheesy Topping:
- 2 cups sharp cheddar cheese, freshly grated
- 1/2 cup mozzarella cheese, shredded
- 2 tablespoons fresh parsley, chopped
Substitution Suggestions: Swap ground beef for ground turkey (93/7) for a leaner option, or use quinoa instead of rice for added protein and fiber.
Timing
This Pioneer Woman-inspired casserole requires just 75 minutes total, which is 25% faster than traditional stuffed pepper recipes:
- Prep Time: 20 minutes
- Cooking Time: 55 minutes
- Total Time: 1 hour 15 minutes
- Serves: 6-8 people generously
The streamlined process eliminates the tedious pepper-stuffing step while maintaining all the authentic flavors you crave.
Preparation Phase
Start by preheating your oven to 350°F and greasing a 9×13-inch baking dish. This temperature ensures even cooking while preventing the rice from becoming mushy or the cheese from burning.
Sautéing the Foundation
Heat a large skillet over medium-high heat and brown the ground beef for 6-8 minutes, breaking it into bite-sized pieces. The key here is achieving a beautiful caramelization that adds depth to your casserole’s flavor profile.
Building the Vegetable Base
Add diced bell peppers and onions to the beef, cooking for 5-7 minutes until the peppers are tender-crisp. This timing preserves the peppers’ vibrant color and slight crunch, mimicking the texture of traditional stuffed peppers.
Creating the Rice Mixture
Stir in minced garlic, uncooked rice, diced tomatoes, beef broth, Worcestershire sauce, oregano, and smoked paprika. The uncooked rice will absorb all the savory flavors during baking, creating a perfectly seasoned base.
Assembly and Baking
Transfer the mixture to your prepared baking dish, cover tightly with foil, and bake for 35 minutes. Remove the foil, top with both cheeses, and bake uncovered for an additional 15-20 minutes until the cheese is golden and bubbly.
Final Touch
Let the casserole rest for 5 minutes before serving, then garnish with fresh parsley for a pop of color and freshness.

Common Mistakes to Avoid
Rice Overcooking: Never pre-cook the rice. The uncooked grains absorb the savory broth during baking, creating the perfect texture. Pre-cooked rice results in a mushy consistency.
Pepper Preparation Errors: Cut peppers into uniform ½-inch pieces to ensure even cooking. Pieces that are too large remain crunchy, while too-small pieces become mushy.
Cheese Timing: Add cheese only during the final 15-20 minutes of baking. Adding it earlier causes burning and separation.
Liquid Ratios: Maintain the 2:1 broth-to-rice ratio. Too little liquid results in undercooked rice, while excess liquid creates a soupy casserole.
Temperature Control: Avoid cooking at temperatures above 350°F, which can cause uneven cooking and dried edges.

FAQs
Can I make this casserole ahead of time?
Absolutely! Assemble the entire casserole up to 24 hours before baking. Cover tightly with plastic wrap and refrigerate. When ready to bake, remove from refrigerator 30 minutes before cooking and add 10 minutes to the covered baking time.
What’s the best way to prevent mushy rice?
Use long-grain white rice and never pre-cook it. The raw rice absorbs the flavorful broth during baking, creating perfectly tender grains. Maintain the proper 2:1 liquid-to-rice ratio for optimal results.
Can I substitute different colored bell peppers?
Yes! Any combination of bell peppers works beautifully. Red and yellow peppers are slightly sweeter, while green peppers offer a more traditional flavor. Orange peppers add vibrant color and mild sweetness.
How do I know when the casserole is fully cooked?
The rice should be tender when pierced with a fork, the cheese should be golden and bubbly, and the internal temperature should reach 165°F. If the rice needs more time, cover with foil and continue baking in 10-minute intervals.
What are the best cheese alternatives for dietary restrictions?
For dairy-free options, use plant-based cheddar and mozzarella alternatives. For reduced calories, try part-skim mozzarella and reduced-fat sharp cheddar. Nutritional yeast adds cheesy flavor for vegan versions.
