Easy Stuffed Pepper Casserole Recipe for Busy Nights

This easy stuffed pepper casserole is a complete one-pan dinner made with lean ground beef, colorful bell peppers, tomatoes, rice, and melted cheese. It takes only 10–15 minutes to prep and about 30–40 minutes to cook, making it a practical 4–6 serving meal for busy weeknights.

Every spoonful has the familiar comfort of classic stuffed peppers without the extra work of hollowing, filling, and baking individual peppers. The rice simmers directly in a savory tomato and beef broth mixture, while Italian seasoning and Worcestershire sauce give the casserole a rich, satisfying flavor before a blanket of cheddar or Monterey Jack melts over the top.

Why You’ll Love This Recipe

Classic stuffed peppers are delicious, but preparing each pepper individually can feel like too much on a crowded evening. This casserole delivers the same familiar combination of seasoned meat, tender peppers, tomato sauce, rice, and cheese in one skillet.

There is no separate pot of rice and no special baking dish required when you use an ovenproof skillet or Dutch oven. The ingredients cook together, which means the rice absorbs the savory broth and tomato flavors instead of tasting like a plain side dish.

• Fast preparation: The vegetables can be chopped while the skillet heats.
• Family-friendly flavor: The seasoning is savory and comforting without being overpowering.
• Flexible serving size: The recipe makes 4–6 portions for dinner or leftovers.
• Simple cleanup: Everything cooks in one large covered skillet.

Ingredients You’ll Need

Lean ground beef forms the savory base of this casserole, while a small yellow onion and garlic build its aromatic foundation. Three diced bell peppers add sweetness, color, and a pleasant tender bite; use a mix of red, green, yellow, or orange peppers for a colorful skillet.

Undrained diced tomatoes and tomato sauce create the saucy element, and two cups of low-sodium beef broth provide the liquid needed to cook the uncooked long-grain white rice. Italian seasoning, Worcestershire sauce, kosher salt, and black pepper keep the flavor balanced and rich.

Finish with one cup of shredded cheddar or Monterey Jack. Cheddar brings a familiar sharpness, while Monterey Jack melts especially smoothly and gives the top a mild, creamy finish.

How to Make It Step-by-Step

Step 1: Heat the olive oil in a large ovenproof skillet or Dutch oven over medium-high heat. Add the ground beef and diced onion, cooking for 5–7 minutes while breaking the beef apart until it is browned and the onion is soft; drain excess fat if necessary.

Step 2: Add the minced garlic and diced bell peppers to the browned beef mixture. Cook for 2–3 minutes, stirring often, until the garlic smells fragrant and the peppers start to soften without losing all of their fresh color.

Step 3: Stir in the undrained diced tomatoes, tomato sauce, beef broth, uncooked rice, Italian seasoning, Worcestershire sauce, kosher salt, and black pepper. Mix carefully from the bottom of the pan so the rice is surrounded by liquid and the seasonings are evenly dispersed.

Step 4: Bring the skillet mixture to a boil, then reduce the heat to low. Cover it with a tight-fitting lid and simmer for 18–22 minutes, stirring once or twice during cooking to prevent sticking and reduce the chance of dry or undercooked spots.

Step 5: Remove the lid and test a few grains of rice for tenderness. The rice should be fully cooked and most of the liquid should be absorbed; if needed, cover the skillet again and cook briefly until the rice reaches the right texture.

Step 6: Sprinkle the shredded cheese across the surface in an even layer. Cover the skillet for 1–2 minutes to melt the cheese, or use the broiler briefly if you prefer a bubbly, lightly browned topping.

Step 7: Turn off the heat and let the casserole rest for 5 minutes before serving. This pause allows the rice to absorb remaining liquid and gives the casserole enough structure to spoon into generous portions.

Pro Tips for the Best Casserole

The most important piece of equipment is a large skillet with a tight-fitting lid. A crowded pan or loose lid can interfere with even steaming, leaving some rice tender and other grains dry or undercooked.

Keep the heat low after the mixture reaches a boil. A gentle simmer gives the rice time to absorb the broth while allowing the peppers to soften without scorching the tomato mixture on the bottom.

Stir only once or twice during the covered cooking time. Too much stirring can release extra starch and make the casserole overly thick, while too little attention may allow rice to stick.

• Dice the peppers evenly so they cook at the same rate.
• Drain the beef only if there is a noticeable amount of excess fat.
• Taste after cooking and add more salt if needed.
• Allow the full 5-minute rest before judging the final consistency.
• Use an oven mitt when moving the skillet because the handle will be hot.

For a little more warmth, add ½ teaspoon smoked paprika or red pepper flakes with the other seasonings. These additions are optional and should complement, rather than hide, the sweet peppers and tomato flavor.

Easy Variations

Ground turkey or ground chicken can replace the beef when you want a lighter-tasting version. Follow the same browning method, making sure the substitute is cooked through before adding the remaining ingredients.

Already have cooked rice in the refrigerator? Use it to shorten the cooking time, reduce the beef broth to about ½ cup, and simmer only until the ingredients are hot and the flavors come together.

Cheddar and Monterey Jack are both excellent choices, but mozzarella, pepper Jack, or a Mexican-style cheese blend can be used for a different finish. Pepper Jack adds noticeable heat, while mozzarella keeps the topping mild and stretchy.

Do not swap brown rice for white rice at the same quantity without changing the recipe. Brown rice generally needs substantially longer cooking and a different amount of liquid, so it requires a separate adjustment rather than a direct substitution.

Serving Suggestions

This casserole is satisfying on its own because it includes protein, vegetables, rice, and cheese. Serve it in shallow bowls so the tomato-rich sauce and melted cheese are included in every portion.

A crisp green salad, steamed green beans, or simple roasted vegetables make easy companions. Warm bread is also useful for scooping up the last bit of sauce, and this soft Hawaiian rolls recipe would make a particularly inviting side for a family dinner.

For dessert, keep the relaxed one-pan theme going with a small sweet treat such as easy KitKat fudge. If you prefer a fruit-based ending, this peach cobbler idea pairs nicely with the cozy flavors of the casserole.

Storage and Reheating

Cool leftovers promptly, then transfer them to a covered refrigerator-safe container. The casserole is convenient for next-day lunches because the rice continues to absorb the tomato broth as it chills.

Reheat individual portions gently in the microwave, stirring as needed, or warm a larger amount in a covered skillet over low heat. If the casserole seems dry after refrigeration, add a small splash of broth or water before reheating.

For meal planning, portion the casserole after its 5-minute rest and let it cool before covering. Keep the cheese topping intact when possible so reheated servings still have a pleasant savory finish.

Make-Ahead Notes

You can prepare the beef, onion, garlic, and peppers ahead of time, then add the tomatoes, sauce, broth, rice, and seasonings when you are ready to cook. This approach shortens the active work during the dinner rush while preserving the best rice texture.

For the best result, cook the rice close to serving time rather than fully preparing the casserole hours in advance. Freshly simmered rice absorbs the liquid more evenly and produces the soft, spoonable texture associated with stuffed pepper casserole.

Ingredients

  

Main Ingredients

• 1 tablespoon Olive oil
• 1 pound Lean ground beef
• 1 small Small yellow onion, diced
• 2 cloves Garlic, minced
• 3 bell peppers Bell peppers, diced
• 1 14–15-ounce can Diced tomatoes, undrained
• 1 8-ounce can Tomato sauce
• 2 cups Low-sodium beef broth
• 1 cup Uncooked long-grain white rice

Seasonings

• 1 teaspoon Italian seasoning
• 1 tablespoon Worcestershire sauce
• 1 teaspoon Kosher salt
• 1/2 teaspoon Black pepper

Topping

• 1 cup Shredded cheddar or Monterey Jack cheese

Method

 

Step-by-Step

1. Heat the olive oil in a large ovenproof skillet or Dutch oven over medium-high heat. Add the ground beef and diced onion, then cook for 5–7 minutes while breaking the meat into small pieces, until the beef is browned and the onion is softened; drain excess fat if needed.
2. Stir in the minced garlic and diced bell peppers. Cook for 2–3 minutes, just until the garlic is fragrant and the peppers begin to soften while still retaining some color.
3. Add the undrained diced tomatoes, tomato sauce, beef broth, uncooked rice, Italian seasoning, Worcestershire sauce, kosher salt, and black pepper. Stir thoroughly so the rice is distributed through the liquid and the seasonings coat the beef and vegetables.
4. Bring the mixture to a boil, then reduce the heat to low. Cover the skillet tightly and simmer for 18–22 minutes, stirring once or twice to keep the rice from sticking and to help it cook evenly.
5. Remove the lid and check the rice for tenderness. Most of the liquid should be absorbed; if the rice needs a little more time, replace the lid and continue cooking briefly until tender.
6. Sprinkle the shredded cheddar or Monterey Jack evenly over the casserole. Cover for 1–2 minutes until the cheese melts, or place the ovenproof skillet under a broiler briefly until the cheese is bubbly.
7. Let the casserole rest for 5 minutes before serving. This short rest allows the rice to absorb remaining liquid and helps the casserole firm up for neat, generous portions.

Notes

Use a large skillet with a tight-fitting lid so the uncooked rice steams evenly. Ground turkey or chicken may replace the beef. For cooked rice, use about 1/2 cup broth and simmer only until the ingredients are hot. Brown rice needs different liquid and cooking adjustments and should not be substituted at the same quantity without changing the method.

Final Thoughts

This easy stuffed pepper casserole brings all the best parts of traditional stuffed peppers to the table with much less preparation. Ground beef, colorful peppers, tomatoes, rice, and melted cheese turn a handful of everyday ingredients into a warm, complete dinner.

Use a tight-fitting lid, keep the rice at a gentle simmer, and remember the 5-minute resting period for the best texture. Once you make it, the flexible ingredient swaps and one-pan cleanup may make this a regular part of your busy-night dinner rotation.

Serve it straight from the skillet with a simple vegetable or warm rolls, and let everyone help themselves. It is the kind of comforting meal that tastes carefully planned even when it comes together on a hectic evening.
