1 tsp paprika: Infuses a smoky warmth that complements the beef beautifully.

Salt and pepper (to taste): Essential seasonings to balance and elevate all the flavors.
1 15 oz. can black beans (drained): Adds creaminess and protein, making the casserole extra filling and nutritious.

How to Make Ground Beef and Butternut Squash Casserole Recipe

Step 1: Preheat the Oven

Start by preheating your oven to 375 degrees Fahrenheit. This temperature is ideal for gently softening the butternut squash and roasting the bell pepper without turning anything mushy, setting the stage for a perfectly textured casserole.

Step 2: Prepare the Vegetables

Place the frozen butternut squash cubes and sliced or chopped bell pepper in your casserole dish. Drizzle them with olive oil to help them roast evenly and bring out their natural sweetness as they cook. Pop them into the oven for about 20 minutes, until the squash starts to soften just a bit but still holds its shape.

Step 3: Drain Excess Liquid

Once the vegetables are roasted, you might notice some liquid in the casserole dish. Carefully drain this off to avoid a watery final dish. This step ensures your casserole keeps that perfect creamy yet firm texture we’re aiming for.

Step 4: Mix in the Flavor and Protein

Next, stir in the paprika, garlic powder, salt, and pepper, letting those spices weave their magic throughout the veggies. Add the drained black beans, cooked ground beef, half of the shredded cheese, and chopped kale. Mix everything gently so all the ingredients are evenly distributed and ready to meld together in the next baking phase.

Step 5: Add the Cheese Topping and Finish Baking

Sprinkle the remaining cheese over the top, creating a golden, gooey layer once baked. Return the casserole to the oven and bake it for another 10 minutes, or until everything is tender and the cheese is nicely melted and bubbly. For a touch of extra flair, sprinkle some crushed red pepper before serving if you want a little heat.

Garnishes

This casserole shines on its own, but you can brighten it up with fresh chopped parsley or a dollop of sour cream for creaminess. A sprinkle of green onions adds a little sharpness and color contrast that makes each serving even more inviting.

Side Dishes

Since the casserole is already packed with flavor, it pairs beautifully with simple sides like a crisp green salad or garlic bread to scoop up all those delicious juices. Roasted Brussels sprouts or steamed green beans also make excellent companions for a well-rounded, hearty meal.

Creative Ways to Present

For a fun twist, try serving the Ground Beef and Butternut Squash Casserole Recipe in individual ramekins or small cast iron skillets for a charming single-serve presentation. You can also layer it over cooked quinoa or rice to turn it into a one-bowl wonder that everyone will rave about.

Make Ahead and Storage

Storing Leftovers

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. This casserole tastes fantastic the next day as the flavors continue to meld, making it a perfect dish for quick lunches or easy dinners during a busy week.

Freezing

If you want more time to enjoy this delicious casserole, it freezes well. Portion it into freezer-safe containers and freeze for up to 3 months. Just thaw overnight in the fridge before reheating for a stress-free meal anytime you want.

Reheating

To reheat, warm individual portions in the microwave for 2-3 minutes or until heated through. For a crispier top, you can reheat larger portions in the oven at 350 degrees Fahrenheit for about 15-20 minutes until bubbly and warm all the way through.
