How to Make Cheeseburger Casserole with Spaghetti Squash
Step 1: Roast the Spaghetti Squash
Start by preheating your oven to 400°F. Grab your largest, sharpest knife and carefully cut the squash in half lengthwise. Scoop out those seeds (an ice cream scoop does wonders here), then drizzle the cut sides with olive oil. Place the halves cut-side down on a parchment-lined baking sheet. They’ll need to roast for 35–40 minutes until tender and golden—the squash should give easily when you poke it with a fork. Let them cool a bit so you can handle them, then use a fork to scrape the flesh into long, noodle-like strands.
Step 2: Brown the Beef
While the squash is roasting, set a large skillet over medium heat. Add the ground beef, breaking it apart with a spoon as it sizzles. Let it cook for 6–7 minutes until perfectly browned. If there’s any excess fat, go ahead and drain it—this keeps the casserole from being greasy.
Step 3: Add Aromatics and Seasonings
Stir in the finely diced onion and garlic, sautéing for about 3 minutes until soft and fragrant. Sprinkle in Worcestershire sauce, mustard, smoked paprika, salt, and black pepper. These little touches infuse the beef with classic cheeseburger punch. Toss in the drained diced tomatoes and tomato sauce, and let everything simmer together for 5 minutes so the flavors can get cozy.
Step 4: Mix It All Together
In a big mixing bowl, combine your spaghetti squash strands with the beef mixture. Stir in half of the cheddar cheese, folding until the cheese melts and the filling comes together like a dream. The mix should be hearty, juicy, and loaded with burger flavor.
Step 5: Layer Up and Bake
Spoon the whole delicious mound into a greased 9×13-inch baking dish. Spread evenly and then top with the remaining cheddar, freshly shredded mozzarella, and a shower of grated Parmesan. Drop the oven temperature to 375°F and bake uncovered for 20–25 minutes. Watch for that cheese to get bubbly and golden—the best sign it’s ready!
Step 6: Add Final Touches
Once out of the oven, sprinkle over chopped pickles and fresh parsley for that signature cheeseburger finish (and loads of color). Slice, serve, and get ready for rave reviews.
How to Serve Cheeseburger Casserole with Spaghetti Squash
Garnishes
This is one of those meals that gets even better with a little flair. A handful of chopped pickles adds a lively zing (and totally channels burger night), while a sprinkle of fresh parsley gives the casserole a beautiful, herby finish. Want to amp up the burger vibes? Try scattering sesame seeds on top, or offer extra ketchup and mustard for drizzling at the table.
Side Dishes
Cheeseburger Casserole with Spaghetti Squash is plenty satisfying on its own, but you can round out the meal with a crisp green salad (think romaine, cherry tomatoes, and a vinaigrette), some roasted broccoli, or even classic oven fries. For a light lunch, try serving it with sliced tomatoes and avocado on the side.
Creative Ways to Present
If you want to impress, spoon the hot casserole into individual ramekins or mini cast iron skillets—everyone loves their own personal serving! For casual parties, offer a “burger bar” with bowls of pickles, chopped lettuce, jalapeños, and favorite burger sauces so guests can top their squares however they like. Leftovers? Stack a portion on a split toasted bun like a “noodle burger” (surprisingly awesome) or warm up with an egg on top for brunch.
Make Ahead and Storage
Storing Leftovers
After devouring your fill, let any leftovers cool to room temperature. Store slices of Cheeseburger Casserole with Spaghetti Squash in airtight containers in the refrigerator for up to 4 days. The flavors deepen, and the texture holds up beautifully—perfect for grab-and-go lunches or quick dinners!
Freezing
This casserole is freezer-friendly! Slice cooled portions into individual servings and wrap tightly in plastic wrap or foil. Pop them into a zip-top freezer bag or airtight container. They’ll keep well for up to 2 months. To enjoy, thaw overnight in the fridge before reheating.
Reheating
Reheat slices in a 350°F oven, covered with foil, for 15–20 minutes until hot and the cheese is melty again. You can also quickly microwave single servings on medium power. If you froze your casserole, let it thaw first for best texture and flavor.
FAQs
Can I use another type Main Course
Absolutely! Ground turkey or chicken are great lean alternatives, and even plant-based crumbles work if you want a vegetarian option. Each version will bring its own vibe, but all are delicious in this dish.
How do I know when the spaghetti squash is roasted enough?
It’s ready when you can easily pierce the skin with a fork and the strands inside shred without much resistance. Undercooked squash will be too crunchy and watery, so make sure it’s nicely tender before moving on.
Is Cheeseburger Casserole with Spaghetti Squash kid-friendly?
Yes! The cheesy, saucy, burger-inspired flavors are usually a big hit, even with picky eaters. If your kids aren’t fans of pickles or onions, you can leave those on the side or finely chop to blend them in.
Can I prep this casserole in advance?
Definitely. You can assemble the casserole up to the point of baking, cover, and refrigerate for up to 24 hours. Just pop it in the oven when you’re ready to eat, adding a few extra minutes to the baking time to ensure it heats through fully.
What makes this recipe low-carb?
Swapping traditional pasta or potatoes for spaghetti squash keeps carbs in check while still delivering that cozy, fun “casserole” feel. Plus, there’s no flour-based thickener—just naturally flavorful ingredients!
