Roasted acorn squash stuffed with seasoned ground beef, creamy refried beans, and lots of melted cheddar and mozzarella cheese. It's like a cheesy burrito tucked inside a roasted squash bowl! Such a delicious and easy fall dinner!
Prep the squash. Preheat your oven to 400°F. Cut each acorn squash in half and scoop out the seeds. Brush with olive oil, sprinkle with salt and pepper, and place cut-side down on a parchment-lined baking sheet.
Roast. Bake for 25–30 minutes, until the squash is starting to soften. We'll finish roasting it after adding the filling!
Cook the beef. Meanwhile, cook the ground beef and chopped onion in a large skillet over medium heat until browned and fully cooked, about 7–10 minutes. Break the meat into small pieces as it cooks and drain any extra grease.
Add the beans. Stir in the taco seasoning and refried beans. Add a little water if the mixture seems too thick, then cook for another 2–3 minutes until everything is heated through.
Make it cheesy! Add half of the cheddar and half of the mozzarella right into the warm beef mixture. Stir until melted and creamy. SO GOOD!
Stuff the squash. Carefully flip the roasted squash halves over and divide the cheesy beef filling evenly between them.
More cheese! Sprinkle the remaining cheddar and mozzarella right over the tops.
Bake until bubbly. Return to the oven for 10–15 minutes, or until the squash is fork-tender and the cheese is melted and bubbly. Add more time if needed.
Add toppings and enjoy! Let cool for a few minutes, then add your favorite toppings. I love avocado, sour cream, diced tomatoes, and cilantro!
Notes
Make chopping easier: Use a veggie chopper for the onion and toppings. It's quick, easy, and gives you evenly sized pieces.
Cheese: Use 1 cup of each cheese for a lighter cheesy filling or 2 cups of each if you love it extra cheesy!
Don't add too much water: You want the filling thick and creamy, not runny.
Make ahead: Roast the squash and prepare the beef filling up to 2 days ahead.
Storage: Refrigerate leftovers for up to 3–4 days.
Reheating: Warm in the oven at 350°F or microwave until heated through to 165°F.
