1 carrot, diced

½ cup corn

½ cup peas

1 red bell pepper, chopped (optional)

1 cup tomato sauce

2 tbsp tomato paste

½ cup beef broth

1 tbsp Worcestershire sauce

Instructions

Preheat Oven
Preheat to 180°C (350°F).

Cook the Beef
Heat oil in a pan, add ground beef, and cook until browned. Break it apart as it cooks.

Add Aromatics
Stir in chopped onion and cook until soft.

Add Vegetables
Add carrots, corn, peas, and bell pepper. Cook 3–4 minutes.

Build the Sauce
Stir in tomato sauce, tomato paste, broth, Worcestershire sauce, and seasonings.

Simmer Briefly
Let mixture simmer for 5–7 minutes to combine flavors.

Assemble Casserole

If using rice: spread uncooked rice in baking dish, then pour beef mixture over it.

If using mashed potatoes: spread beef mixture first, then top with mashed potatoes.

Cover & Bake
Cover with foil and bake for 25–30 minutes (longer if using rice, about 40–45 minutes total).

Add Cheese
Remove foil, sprinkle cheese evenly on top.

Final Bake
Bake uncovered for 10–15 minutes until cheese is melted and bubbly.

Tips

Drain excess fat to avoid greasy casserole.

Use freshly grated cheese for better melting.

Rinse rice well to remove starch and prevent clumping.

Add broth gradually if using rice to ensure it cooks properly.

Don’t overcook vegetables before baking; they’ll soften more in the oven.

Season in layers for deeper flavor.

Cover tightly with foil to trap steam for rice cooking.

Let it rest 5–10 minutes before serving for cleaner slices.

Use a deep dish to prevent overflow.

Taste before baking and adjust seasoning.
