Step-by-Step Instructions 📋

Let’s walk through the process from squash to casserole. It’s easier than you think—and your kitchen will smell amazing along the way.

🔥 Step 1: Roast the Spaghetti Squash

  1. Preheat your oven to 400°F (200°C).
  2. Line a baking sheet with parchment paper.
  3. Cut the spaghetti squash in half crosswise, not lengthwise—this helps produce longer “noodle” strands.
  4. Scoop out the seeds and stringy pulp.
  5. Place squash halves cut-side down on the baking sheet.
  6. Roast for 40 minutes, or until the squash feels tender and squeezable.

🧠 Why cut it crosswise? It preserves the natural long spaghetti-like strands, perfect for the pasta-like texture we’re aiming for.

🥓 Step 2: Cook the Bacon

  1. While the squash is roasting, heat a large skillet over medium heat.
  2. Add the chopped bacon and cook until crispy, about 6–8 minutes.
  3. Use a slotted spoon to transfer the bacon to a paper towel-lined plate, leaving the bacon grease in the pan.

🍖 Step 3: Brown the Ground Beef

  1. In the same skillet (bacon grease adds flavor!), add the ground beef.
  2. Break up any clumps with the back of a wooden spoon.
  3. Cook for about 7 minutes, until the meat is mostly browned.

🧄 Step 4: Add Garlic & Seasonings

  1. Add the minced garlic, salt, and pepper to the beef.
  2. Cook for 2–3 more minutes, until fully browned and fragrant.

🍅 Step 5: Sauce It Up

  1. Stir in the sugar-free ketchup and Worcestershire sauce.
  2. Mix well and reduce heat slightly while the squash finishes roasting.

🍝 Step 6: Add the Spaghetti Squash

  1. Remove the roasted squash from the oven.
  2. Carefully scoop out the flesh with a fork—it should come out in beautiful, pasta-like strands.
  3. Stir the strands directly into the beef mixture in the skillet, combining everything thoroughly.

🧀 Step 7: Top with Cheese and Melt

  1. Spread the mixture evenly in the skillet.
  2. Sprinkle with the shredded cheddar cheese.
  3. Cover the skillet with a lid or foil.
  4. Let it sit on low heat for 5 minutes, just until the cheese is gooey and melted.

🥓 Step 8: Garnish and Serve

  1. Sprinkle the crispy bacon bits over the top.
  2. Serve warm and enjoy every bite!

FAQs ❓

Here are answers to the top questions about Cheeseburger Spaghetti Squash Casserole!

1. Can I make this casserole dairy-free?

Yes! Swap the cheddar with dairy-free cheese shreds or nutritional yeast for a cheesy flavor without dairy.

2. Is this recipe gluten-free?

Absolutely—just double-check that your Worcestershire sauce is gluten-free.

3. Can I use ground turkey instead of beef?
