Recipe Details

• Servings: 6
• Prep Time: 15 minutes
• Cook Time: 40 minutes
• Total Time: 55 minutes
• Cooking Method: Oven-baked

 

Ingredients

• 1 pound ground beef
• 1 onion, chopped
• 2 cloves garlic, minced
• 1 cup carrots, sliced
• 1 cup celery, sliced
• 1 cup frozen peas
• 1 can (14.5 oz) diced tomatoes, drained
• 1 cup beef broth
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• Salt and pepper to taste
• 2 cups shredded cheddar cheese
• 1 cup breadcrumbs
• 2 tablespoons olive oil

 

Directions

1. Preheat the oven. Set your oven to 375°F (190°C).
2. Cook the onion and garlic. Heat the olive oil in a large skillet over medium heat. Add the chopped onion and minced garlic, cooking until the onion softens and becomes translucent.
3. Brown the beef. Add the ground beef and cook, breaking it into small pieces with a spoon, until browned and cooked through. Drain excess fat if needed.
4. Add the vegetables. Stir in the carrots, celery, and frozen peas. Cook for about 5 minutes, stirring occasionally.
5. Make the beef mixture. Add the drained diced tomatoes and beef broth. Stir in the dried thyme, oregano, salt, and pepper. Let the mixture simmer for about 10 minutes so the flavors can come together.
6. Transfer to a baking dish. Spoon the beef and vegetable mixture into a rectangular baking dish and spread it into an even layer.
7. Add the topping. Sprinkle the shredded cheddar cheese over the casserole. In a small bowl, mix the breadcrumbs with a little olive oil, then scatter them evenly over the cheese.
8. Bake until golden. Bake for 25–30 minutes, or until the topping is golden and crisp and the casserole is bubbling around the edges.
9. Rest and serve. Let the casserole stand for a few minutes before serving. This helps the layers settle and makes it easier to spoon onto plates.

 

Variations & Tips

• Use ground turkey or chicken: Replace the ground beef with ground turkey or chicken if you prefer a different protein.
• Add extra vegetables: Chopped bell peppers or zucchini can be added with the other vegetables.
• Make it spicy: Add a pinch of red pepper flakes or a little hot sauce to the beef mixture.
• Try a gluten-free topping: Use certified gluten-free breadcrumbs, or leave them out if you prefer a cheesy topping.
• Get a crispier crust: For extra crunch, make sure the breadcrumbs are lightly coated with olive oil before sprinkling them over the casserole.
• Check the vegetables: Slice the carrots thinly so they have enough time to become tender during cooking and baking.

 

What to Serve With Beef and Vegetable Casserole

• This casserole is filling on its own, but a simple side dish can round out the meal.
• Green salad: Fresh greens with a light vinaigrette provide a refreshing contrast.
• Steamed green beans: A simple vegetable side complements the savory beef and cheese.
• Crusty bread or dinner rolls: Serve warm bread alongside the casserole to enjoy the flavorful juices.
• Mashed potatoes: A small serving makes the meal even heartier.
• Iced tea: A chilled glass of iced tea is a refreshing choice for a casual family dinner.

 

Storage & Reheating

• Allow leftovers to cool, then transfer them to an airtight container and refrigerate within two hours of cooking. Store in the refrigerator for up to 3–4 days.
• To reheat, place a portion in an oven-safe dish and warm it at 350°F (175°C) until heated through. Cover loosely with foil if the breadcrumb topping starts browning too quickly. Individual portions can also be reheated in the microwave, although the topping may become softer.
• For longer storage, freeze cooled portions in freezer-safe containers. Thaw overnight in the refrigerator before reheating, and make sure the casserole is thoroughly hot before serving.

 

Frequently Asked Questions

Can I prepare this casserole ahead of time?

Yes. You can prepare the beef and vegetable mixture ahead, refrigerate it, and assemble the casserole with the cheese and breadcrumb topping before baking. If the mixture is cold, it may need additional time in the oven.

Can I use fresh peas instead of frozen peas?

Yes. Fresh peas work well in this recipe. Add them with the other vegetables and cook until they begin to soften.

How do I know when the casserole is ready?

The topping should be golden brown, and the filling should be bubbling around the edges. The carrots should also be tender.

Can I make it without breadcrumbs?

Yes. Simply leave them out for a cheesy top, or use a gluten-free alternative if needed.
