Common Mistakes to Avoid

1. Overcooking the beef — Cook just until browned and cooked through; excessive cooking can make the casserole dry.

2. Leaving too much liquid in the skillet — Drain excess grease or moisture before baking so the finished casserole isn’t watery.

3. Cutting the vegetables too large — Thinly slicing the peppers and onions helps them soften evenly during cooking.

4. Using too much cheese — A generous layer is delicious, but excessive cheese can make the dish overly greasy and significantly increase calories.

Required Equipment

• Large skillet — Provides enough space to brown the beef and sauté the vegetables evenly.

• Wooden spoon or spatula — Makes it easy to break up the ground beef while cooking.

• 9 × 13-inch baking dish — Gives the casserole enough surface area for even baking and browning.

• Chef’s knife — Makes quick, even cuts through the peppers and onions.

• Measuring cups and spoons — Keep the ingredient ratios consistent for reliable results.

Storage Instructions

Allow the casserole to cool slightly before transferring leftovers to airtight containers or covering the baking dish tightly with foil.

• Refrigerator: Store for up to 4 days.

• Freezer: Freeze individual portions in freezer-safe airtight containers for up to 2–3 months for best quality.

• Reheating: Thaw frozen portions overnight in the refrigerator when possible, then microwave until hot or reheat covered in a 350°F (175°C) oven until warmed through.

• For the best high-protein-friendly meal prep, portion the casserole before storing so serving sizes are easy to manage.

📝 Ingredients

• 1½ lb (680 g) lean ground beef — 90% lean recommended

• 1 medium green bell pepper, thinly sliced

• 1 medium yellow or red bell pepper, thinly sliced

• 1 medium yellow onion, thinly sliced

• 2 cloves garlic, minced

• 1 tablespoon olive oil

• 1 tablespoon Worcestershire sauce

• 1 teaspoon Italian seasoning

• ½ teaspoon salt

• ½ teaspoon black pepper

• 6 oz (170 g) cream cheese, softened

• 1½ cups (170 g) shredded provolone cheese

• ½ cup (55 g) shredded mozzarella cheese

Ingredient note: For a leaner, higher-protein version, choose 90–93% lean ground beef. Reduced-fat cream cheese can also lower the overall fat content, although the texture may be slightly less rich.

Directions

1. Preheat the oven.
   Heat oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish.

2. Brown the beef.
   Heat a large skillet over medium-high heat and add the olive oil. Add the ground beef and cook for 6–8 minutes, breaking it apart, until browned and no longer pink. Drain excess grease if needed.

3. Cook the vegetables.
   Reduce heat to medium. Add the sliced peppers and onion and sauté for 5–7 minutes, stirring occasionally, until softened but not mushy.

4. Build the flavor.
   Add garlic, Worcestershire sauce, Italian seasoning, salt, and black pepper. Cook for another 1–2 minutes, until fragrant.

5. Add the cream cheese.
   Reduce heat to low and stir in the softened cream cheese until it melts into the beef mixture. The mixture should look creamy and evenly coated.

6. Transfer to the baking dish.
   Spread the beef and vegetable mixture evenly into the prepared dish. Sprinkle provolone and mozzarella over the top.

7. Bake until bubbly.
   Bake uncovered at 375°F (190°C) for 15–18 minutes, until the cheese is completely melted and bubbling around the edges.

8. Brown the top.
   For a more golden finish, switch to broil/high heat for 1–2 minutes, watching carefully so the cheese doesn’t burn.

9. Rest before serving.
   Let the casserole rest for 5 minutes. The cheese should settle slightly while remaining gooey, and the filling should hold together when served.

High-protein cooking tip: Avoid adding breadcrumbs, pasta, or a traditional hoagie roll to the casserole. Keeping the beef as the main ingredient maintains its protein-forward, low-carb character.
