Step-by-Step Instructions
Cooking spaghetti squash lasagna boats may sound complicated, but it’s actually straightforward. Follow these steps for the best results.
Step 1: Roast the Spaghetti Squash
- Preheat your oven to 400°F (200°C).
- Carefully slice the spaghetti squash in half lengthwise using a sharp chef’s knife.
- Pro Tip: Microwave the whole squash for 3–5 minutes first to soften it and make cutting safer.
- Scoop out the seeds and stringy pulp.
- Drizzle the cut sides with olive oil and sprinkle with salt and pepper.
- Place the squash halves cut-side down on a baking sheet.
- Roast for 45–60 minutes until fork-tender.
- Allow to cool slightly before handling.
Step 2: Prepare the Meat Sauce
- Heat a large skillet over medium heat.
- Add olive oil, then the ground beef. Cook until browned, breaking it into small crumbles.
- Drain excess grease if necessary.
- Stir in marinara sauce and Italian seasoning.
- Simmer for 5–7 minutes to blend the flavors.
- Taste and adjust seasoning with salt and pepper.
Step 3: Mix the Ricotta Filling
- In a bowl, combine ricotta cheese, 1 cup mozzarella, Parmesan, Italian seasoning, salt, and pepper.
- Stir until smooth and creamy.
Step 4: Assemble the Boats
- Use a fork to gently scrape the roasted squash into spaghetti-like strands while keeping them inside the shells.
- Stir in half the meat sauce with the squash strands.
- Spread the ricotta mixture over the top.
- Add the remaining meat sauce.
- Sprinkle with the remaining mozzarella.
Step 5: Bake to Perfection
