- Ground beef. Use the leanest kind as you will be draining all excess fat and liquid anyway after cooking.
- Black beans. I used low-sodium black beans that I rinsed and drained really well.
- Corn. I used canned sweet corn kernels that I drained really well.
- Canned green chiles. I used the mild variety. If you like your food spicier, use medium or hot.
- Green onions. Chopped green onions are milder than regular onions, and work great as garnish!
- Pepper jack cheese and cheddar cheese. It's always best to shred or grate the cheese yourself!
How to make ground beef stuffed acorn squash
1) Prepare the acorn squash. You will need 2 medium-sized squashes. First, carefully slice each acorn squash in half. Drizzle the cut sides and the insides of the squash with olive oil and season with salt and pepper.
2) Roast the squash cut sides down in the preheated oven at 400 F for 30 minutes. Remove from oven and turn the squash cut sides up.
3) Make the filling. While the acorn squash is in the oven, cook the ground beef in a large skillet until cooked through. Drain any fat or liquids. Add spices, black beans, corn, green chiles, and green onions. Season the mixture.
4) Stuff the squash. Divide the ground beef mixture among the 4 roasted acorn squash halves until the mixture is leveled.
5) Top with shredded pepper jack and cheddar cheese and bake. Return to the oven and roast for about 15 or 20 minutes at 400 F until the cheese melts.
- To use cooking time efficiently, make the ground beef filling while you roast the acorn squash in the oven.
- Broil the stuffed acorn squash briefly (for about 5 minutes) in the oven until the cheese mixture turns golden here and there. Watch the squash carefully - it can burn easily.
Substitutions and variations
- Winter squash. This is a great recipe to use all kinds of winter squash. Use this Southwestern-style ground beef stuffing to stuff butternut squash or spaghetti squash.
- Ground beef can be replaced with ground turkey or ground chicken. Or, use a plant-based alternative to make this recipe meatless.
- Cheese. This recipe uses Pepper Jack and Cheddar cheeses that go really well with Southwestern flavors. However, you can use a variety of other cheeses instead. You can use shredded Mozzarella (part-skim, low-moisture), Gruyere cheese, Asiago, Provolone, or Fontina cheese.
- Beans. I used canned black beans that I rinsed and drained really well. You can also use canned garbanzo beans, cannellini beans, or pinto beans.
Storage and reheating tips
- Fridge. Refrigerate the leftover ground beef stuffed acorn squash in an airtight container for up to 5 days.
- Reheat in the oven. Reheat it in the preheated oven at 350 F for about 30 minutes.
- Reheat in the microwave oven. You can also microwave the leftovers. For the best and fastest results, you can take the ground beef filling out of the squash and reheat this mixture and the squash separately. Then stuff this mixture back into the acorn squash.
Can you make it ahead?
Of course! Follow these tips:
- You can assemble the whole dish (including the cheese on top) in an oven-safe large pan, cover it with the lid (or foil), refrigerate it, and bake it within 3 days. Because all the ingredients are already cooked, this dish is perfect for meal prep!
- Another option is to roast the acorn squash up to 3 days in advance and then proceed with the rest of the recipe when you're ready.
