Cooking Directions

Step-by-Step Preparation Method

Step 1: Roast the Spaghetti Squash

1. Preheat oven to 400°F (200°C).

3. Brush the cut sides with olive oil, and season with salt and pepper.
4. Place cut-side down on a baking sheet and roast for 30–35 minutes, or until tender.

Step 2: Prepare the Garlic Parmesan Sauce

1. In a large skillet, melt butter over medium heat (or heat olive oil).
2. Add minced garlic and red pepper flakes (if using), sauté for 1–2 minutes until fragrant.
3. Stir in broth, heavy cream (if using), and Parmesan cheese, stirring until smooth.
4. Season with salt and black pepper to taste.

Step 3: Combine Spaghetti Squash and Sauce

1. Add roasted spaghetti squash strands to the skillet.
2. Toss gently to coat evenly with the garlic Parmesan sauce.

Recipe Tips

• Even roasting: Slice squash evenly to ensure uniform cooking.
• Avoid watery sauce: Use freshly grated Parmesan and simmer sauce gently.
• Add protein: Toss in cooked chicken, sausage, or shrimp for a heartier meal.
• Make it creamy: Stir in heavy cream or a splash of milk to make sauce richer.
• Extra flavor: Add fresh herbs like thyme, oregano, or basil.

Variations

1. Vegetable Boost: Add sautéed mushrooms, spinach, or cherry tomatoes.

5. Herb-Infused: Add fresh sage, thyme, or rosemary to the sauce for an earthy twist.

Freezing and Storage

• Refrigerator: Store cooked spaghetti squash and sauce separately in airtight containers for 3–4 days. Reheat gently on stovetop.
• Freezer: Best to freeze squash strands separately from sauce for up to 2 months. Thaw in refrigerator before reheating.
