• 1/2 tsp garlic powder: Adds savory depth without overpowering.
• Salt and pepper to taste: Essential for bringing out all the other flavors.
• 1 15 oz. can black beans (drained): Provides creaminess and a protein boost.
• 1 cup cooked ground beef: The hearty centerpiece that makes this a filling meal.
• 1 cup shredded cheese: Melts into gooey perfection, uniting every ingredient.

How to Make Ground Beef and Butternut Squash Casserole

Step 1: Preheat and Prepare the Vegetables

Set your oven to 375 degrees F to get it nice and hot for roasting. Toss the frozen butternut squash cubes and sliced bell pepper into your casserole dish, then drizzle with olive oil so everything gets a lovely, golden roast. This first roasting step helps bring out the natural sweetness of the squash and softens the peppers to add great texture.

Step 2: Roast the Squash and Peppers

Pop the dish in the oven and bake for about 20 minutes, just until the squash starts to soften. This timing is perfect because the vegetables will continue cooking when the casserole bakes again later. Don’t forget to drain any liquid that pools in the casserole dish after roasting — this way your dish won’t turn out watery and will keep a perfect consistency.

Step 3: Mix in the Flavorful Ingredients

Once the squash and peppers have roasted, it’s time to bring the casserole together. Sprinkle in the paprika, garlic powder, salt, and pepper. Add the drained black beans, cooked ground beef, half of the shredded cheese, and chopped kale. Stir everything gently to combine, making sure cheese and spices spread evenly for maximum flavor in every bite.

Step 4: Cheese It Up and Final Bake

Top the mixture with the remaining shredded cheese so it melts into a golden crust while baking. Place the casserole back into the oven and bake for an additional 10 minutes, or until all the ingredients are tender and the cheese is bubbly and slightly browned. If you want a little extra heat, finish it off with a sprinkle of crushed red pepper for a subtle fire that wakes up your taste buds.

Step 5: Ready to Serve

Remove the casserole from the oven and let it cool just a bit before serving. This resting time helps firm up the layers so the casserole slices beautifully onto plates, and every ingredient has settled into pure flavor harmony.

Garnishes

A simple dollop of sour cream, a handful of fresh chopped parsley or cilantro, or even some sliced green onions add the perfect fresh contrast to this hearty casserole. These garnishes brighten each bite and add lovely color that makes your dish look as great as it tastes.

Side Dishes

Pair this casserole with a crisp green salad dressed with lemon vinaigrette or some warm, crusty bread to soak up any extra juices. Light sides balance the rich, cheesy casserole, making your meal well-rounded and satisfying without feeling too heavy.

Creative Ways to Present

For a family-style dinner, serve the Ground Beef and Butternut Squash Casserole straight from the baking dish so everyone can help themselves. Alternatively, spoon it into individual ramekins for a polished, personalized touch perfect for dinner guests or holiday gatherings. Either way, it’s sure to impress due to its vibrant colors and irresistible aroma.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers (which might be hard!), store them in an airtight container in the refrigerator. The casserole keeps well for up to 3-4 days, making it easy to enjoy a quick, nourishing meal during your busy week.

Freezing

This casserole freezes wonderfully. Place portions into freezer-safe containers or bags and freeze for up to 2 months. When you want a comforting dish fast, just thaw overnight in the fridge and reheat — no extra cooking required.

Reheating

For best results, reheat your Ground Beef and Butternut Squash Casserole in the oven at 350 degrees F until warmed through, about 15-20 minutes. If you’re short on time, a microwave works too but keep it covered to avoid drying out the cheese and squash.

FAQs

Can I use fresh butternut squash instead of frozen?

Yes! If using fresh butternut squash, peel and cube it before roasting. It may require a slightly longer roasting time to soften, but the flavor will be just as delicious.

Is there a vegetarian version of this casserole?

Definitely! Simply omit the ground beef and add extra beans or cooked lentils for protein. You could also swap in sautéed mushrooms or a plant-based ground meat alternative for a satisfying vegetarian twist.

What cheese works best in this casserole?

Cheddar is a classic choice that melts beautifully and provides a sharp, savory flavor. However, feel free to experiment with mozzarella, Monterey Jack, or a cheese blend depending on your taste preferences.

Can I prepare this casserole ahead of time and bake later?

Absolutely! Assemble the casserole up to the baking step, cover tightly, and refrigerate overnight. When ready, bake as directed but add a few extra minutes to the cooking time to ensure it’s heated through.

How spicy is the casserole with crushed red pepper?

The crushed red pepper adds a mild, gentle heat that enhances the flavors without overpowering. If you prefer a spicier kick, feel free to add more according to your taste, or leave it out entirely for a milder dish.
