Ingredients You’ll Need
This Ground Beef and Butternut Squash Casserole shines because of its simple yet well-chosen ingredients. Each one plays an important role in bringing together a dish that’s both satisfying and nutritious.
- 1 lb frozen butternut squash, cubed: The star of the dish, offering sweetness and creamy texture when baked.
- 1 large bell pepper (sliced or chopped): Adds a bright crunch and a splash of color to keep things lively.
- 1 Tbsp olive oil: Helps everything bake evenly and brings out the natural flavors.
- 1 tsp paprika: Infuses a gentle smoky warmth that pairs beautifully with the beef.
- 1/2 tsp garlic powder: Elevates the savory notes without overpowering the other flavors.
- Salt and pepper (to taste): Essential for balancing and enhancing all the ingredients.
- 1 15 oz. can black beans (drained): Adds protein, fiber, and a creamy bite to the casserole.
- 1 cup cooked ground beef: Brings hearty richness and depth to every forkful.
- 1 cup shredded cheese: Provides melty, gooey goodness that ties the dish together.
- 1 cup chopped kale: A nutrient-packed green that adds color and earthiness.
- 1/4 tsp crushed red pepper (optional): For those who like a little kick and extra depth of flavor.
How to Make Ground Beef and Butternut Squash Casserole
Step 1: Preheat the Oven
Start by heating your oven to 375 degrees Fahrenheit. This temperature is perfect for gently roasting the squash so it softens just right without drying out.
Step 2: Prepare the Squash and Peppers
Place the frozen butternut squash cubes and sliced bell pepper in your casserole dish. Drizzle everything with olive oil, making sure each piece has a light coating — this helps with roasting and flavor development.
Step 3: Initial Bake
Bake the squash and pepper mixture for about 20 minutes. You’ll want the squash to begin softening but still hold its shape, which provides a great texture contrast once the rest of the ingredients are added.
Step 4: Drain Excess Liquid
Once roasted, check your casserole dish for any extra liquid and drain it off. Removing the moisture ensures your casserole won’t turn soggy and the flavors will stay concentrated.
Step 5: Mix in the Seasonings and Main Ingredients
Now it’s time to add the magic. Stir in the paprika, garlic powder, salt, and pepper, followed by the drained black beans, cooked ground beef, half of the shredded cheese, and chopped kale. Mix everything gently but thoroughly so every bite is bursting with flavor.
Step 6: Add the Final Cheese Layer
Sprinkle the remaining shredded cheese evenly over the top. This final cheesy layer will melt and create a delicious, gooey topping that makes this Ground Beef and Butternut Squash Casserole a true crowd-pleaser.
Step 7: Final Bake
Pop the casserole back into the oven for another 10 minutes. This final bake lets all the ingredients meld together while softening the kale and melting the cheese to golden perfection.
Step 8: Optional Topping and Serve
If you want a little extra heat, sprinkle crushed red pepper over the top before serving. Then, dive right in and enjoy the warm, hearty goodness of your Ground Beef and Butternut Squash Casserole.
How to Serve Ground Beef and Butternut Squash Casserole

Garnishes
Fresh herbs like parsley or cilantro add a pop of green freshness and brighten the rich flavors. A dollop of sour cream or a sprinkle of sliced green onions can also add a lovely contrast in creaminess and flavor.
Side Dishes
This casserole is pretty complete on its own, but if you want to round out your meal, a crisp salad with a zesty lemon vinaigrette or some crusty bread can be fantastic companions. Light, refreshing sides help balance the warmth and heartiness of the casserole.
Creative Ways to Present
For a fun twist, serve the casserole scooped over a bed of fluffy quinoa or rice. Alternatively, spoon it into individual ramekins for a charming presentation perfect for dinner parties or cozy nights in.
Make Ahead and Storage
Storing Leftovers
Ground Beef and Butternut Squash Casserole keeps beautifully in an airtight container in the fridge for up to 3 days, making it a convenient option for quick lunches or dinners later in the week.
Freezing
If you want to make this casserole well ahead of time, it freezes wonderfully. Just cool completely, transfer into a freezer-safe container, and store for up to 3 months. When ready, thaw overnight in the fridge for best results.
Reheating
To reheat, simply warm individual portions in the microwave or place the whole casserole back in a 350-degree Fahrenheit oven until heated through and the cheese is bubbly once again. Adding a few extra minutes can help revive that freshly baked flavor.
FAQs
Can I use fresh butternut squash instead of frozen?
Absolutely! Fresh butternut squash works great; just peel, cube, and roast it in the same way. It might take a little longer to soften during baking, so keep an eye on it.
Is this casserole gluten-free?
Yes, with these ingredients, the Ground Beef and Butternut Squash Casserole is naturally gluten-free, making it a safe and tasty choice for those avoiding gluten.
Can I substitute the ground beef with another protein?
Definitely! Ground turkey, chicken, or even plant-based crumbles would work nicely and offer a different flavor profile while maintaining the dish’s heartiness.
Is it possible to make this vegetarian?
Yes, you can omit the ground beef and add extra beans, lentils, or tofu for protein. Don’t forget to use a cheese that suits your dietary preferences, or try a plant-based cheese alternative.
How spicy is the casserole with crushed red pepper?
The crushed red pepper adds just a mild to moderate kick, which is optional and adjustable based on your spice tolerance. Feel free to skip it or add more if you like things fiery.
Final Thoughts
