Summer Beef Casserole

Summer Beef Casserole came together for me during a hot July evening when I had leftover ground beef and a fridge full of seasonal vegetables. I didn’t want something heavy but I needed dinner that would feed a hungry crew and still feel fresh. I tossed everything into one dish with a light sauce and a sprinkle of cheese and it turned out so good it instantly made the regular dinner rotation.

What I love about this casserole is that it’s hearty enough to satisfy but still bright and full of color from all the summer produce. It’s the kind of meal you can prep ahead and pop in the oven after a busy day and it’s flexible enough to use whatever’s in season or what you already have on hand.

Ingredients:

Here’s what I use for this recipe. You can always make substitutions if you prefer!

• Ground beef – The protein base that brings richness and heartiness
• Zucchini – Adds moisture and freshness without overpowering
• Corn – Brings sweetness and summer flair to every bite
• Cherry tomatoes – Bursting with juicy flavor that roasts beautifully
• Onion – Adds depth and a little bite to balance the sweetness
• Garlic – Gives the whole dish a savory aromatic base
• Olive oil – Used to sauté and keep everything from sticking
• Pasta or rice – Makes it filling and turns it into a full meal
• Tomato sauce – Lightly coats everything for a cohesive flavor
• Mozzarella or cheddar – Melts beautifully on top for that golden cheesy crust
• Fresh basil or parsley – Brings brightness at the end

Tools You’ll Need

• Large Skillet or Sauté Pan – Used to brown the beef and sauté veggies
• Cutting Board and Knife – For chopping all the fresh summer vegetables
• Mixing Bowl – For combining all the ingredients before baking
• 9×13 Casserole Dish – Perfect for layering and baking everything together
• Wooden Spoon or Spatula – Helps mix without breaking the veggies
• Cheese Grater – If you’re shredding your own cheese for that extra melt

Instructions

Step 1: Preheat the Oven

I preheat the oven to 375°F so it’s hot and ready by the time everything is assembled.

Step 2: Brown the Beef

In a large skillet I cook the ground beef with a little olive oil breaking it apart until it’s browned and cooked through then I drain any excess fat.

Step 3: Sauté the Veggies

In the same pan I add a bit more oil and sauté the onion garlic zucchini corn and cherry tomatoes for about 5–7 minutes until softened but still colorful.

Step 4: Add Sauce and Combine

I stir in the tomato sauce and cooked pasta or rice into the beef and veggie mixture then season everything with salt pepper and a pinch of Italian herbs if I’m feeling extra.

Step 5: Assemble the Casserole

I transfer the mixture to a greased 9×13 dish and spread it out evenly then I sprinkle a generous handful of cheese on top.

Step 6: Bake Until Bubbly

I bake the casserole for 20–25 minutes until the cheese is melted and bubbling and the edges are golden.

Step 7: Add Fresh Herbs

Just before serving I sprinkle chopped fresh basil or parsley over the top for a fresh finish.

Tips

Use whatever summer veggies you have on hand like bell peppers eggplant or green beans
