Ingredients
To make this simple and delicious casserole, here’s what you’ll need:
For the beef:
- 1 tablespoon oil (canola, avocado, or sunflower oil)
- 1 pound ground beef (medium or lean)
- ½ teaspoon salt
- ¼ teaspoon black pepper
For the vegetables:
- 1 large onion, sliced
- 2 red bell peppers, diced
- 4 ribs celery, diced
- 1 tablespoon dried oregano
- ¼ teaspoon salt
- Pinch of black pepper
For the potato bake:
- 1 jar marinara sauce (23 ounces)
- 1 cup cream (35%)
- 1.5 pounds potatoes (Russet or Yukon Gold), peeled and thinly sliced
- ¼ cup grated parmesan
- 1 ball fresh mozzarella, drained and sliced
Step-by-Step Instructions
Let’s make this cheesy ground beef and veggie bake together! Follow these simple steps, and you’ll have a delicious, comforting dinner in no time.
1. Preheat the oven
Start by preheating your oven to 350°F (180°C). This will ensure it’s ready when your casserole is assembled.
2. Cook the ground beef
Heat the oil in a skillet over medium-high heat. Add the ground beef, breaking it up with a spatula as it cooks.
Sprinkle in the salt and pepper, and cook until the beef is browned. Remove the beef from the skillet with a slotted spoon and set it aside, leaving the fat in the pan.
3. Sauté the vegetables
In the same skillet, add the onion, bell peppers, celery, oregano, salt, and a pinch of black pepper. Cook the vegetables over medium heat, stirring occasionally, until softened. Once done, remove the skillet from the heat and set it aside.
4. Mix the sauce
In a jug or small bowl, stir together the marinara sauce and cream. This creamy sauce will bring all the layers together beautifully.
5. Assemble the casserole
In a greased casserole dish, layer the thinly sliced potatoes evenly across the bottom. Spread the cooked ground beef over the potatoes, followed by the sautéed vegetables. Pour the creamy marinara sauce evenly over everything, then sprinkle the grated parmesan on top.
6. Bake covered
Cover the casserole dish tightly with foil and place it in the preheated oven. Bake for 1 hour to allow the potatoes to become tender and the flavors to meld together.
7. Add the mozzarella
After 1 hour, carefully remove the foil from the casserole. Lay the sliced mozzarella on top and return the dish to the oven. Bake for an additional 10 minutes, or until the cheese is melted and golden brown.
8. Let it rest
Remove the casserole from the oven and let it sit for 10 to 15 minutes before serving. This helps the layers settle and makes it easier to slice and serve.
How to Serve Your Cheesy Ground Beef & Veggie Bake
This casserole is a complete meal on its own, thanks to the hearty potatoes, protein-packed beef, and hidden veggies.
- For a little extra color and crunch, serve it with a simple green salad or a side of steamed broccoli. A crusty piece of bread or garlic toast is also a fantastic addition to soak up any extra sauce.
- For a cozy family dinner, set this casserole in the center of the table and let everyone dig in. It’s perfect for casual gatherings or even as a meal prep option for the week!
Storing and Enjoying Leftovers
Got leftovers? Lucky you! This cheesy ground beef and veggie bake stores beautifully.
- Refrigeration: Place leftovers in an airtight container and store in the fridge for up to 3 days.
- Freezing: For longer storage, portion the casserole into freezer-safe containers and freeze for up to 2 months. Thaw in the fridge overnight before reheating.
- Reheating: Warm individual portions in the microwave or reheat the entire casserole in the oven at 350°F (180°C) until heated through.
Top Tips for Customizing Your Cheesy Ground Beef & Veggie Bake
- Swap the beef: Ground turkey, chicken, or even plant-based crumbles work well if you’re looking for a lighter or vegetarian option.
- Add more veggies: Feel free to toss in zucchini, spinach, or mushrooms for extra nutrients. Just sauté them with the other vegetables.
- Spice it up: Add a pinch of red pepper flakes or a dash of hot sauce to the marinara cream mixture for a little heat.
- Cheese options: Try shredded cheddar or gouda instead of mozzarella for a different cheesy twist.
Your Questions About Cheesy Ground Beef & Veggie Bake Answered
Can I make this casserole ahead of time?
Yes! Assemble the casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours. When ready to bake, add an extra 10 minutes to the covered cooking time.
Can I use sweet potatoes instead of regular potatoes?
Absolutely! Sweet potatoes add a delicious sweetness and pair beautifully with the savory beef and creamy sauce.
How can I make this dish healthier?
To lighten it up, use lean ground beef, swap heavy cream for a lighter alternative, and add even more vegetables to the mix.
What’s the best way to slice the potatoes?
To get thin, even slices, use a mandoline slicer if you have one. If not, a sharp knife works just fine—just take your time to slice the potatoes as evenly as possible.
