Frequently Asked Questions
Can I freeze spaghetti squash lasagna?
Yes! This recipe freezes beautifully. Just assemble, cool completely, and store in freezer-safe containers.
How do I reheat from frozen?
For best results, thaw overnight in the fridge and bake at 350°F for 35–40 minutes until heated through.
Why is my spaghetti squash watery?
Spaghetti squash naturally releases water. Roasting it instead of microwaving helps reduce excess moisture.
Can I make this ahead for the week instead of freezing?
Absolutely. Store in the fridge for up to 4 days and reheat as needed.
Can I substitute the turkey sausage?
Yes! You can use lean ground beef, chicken sausage, or even keep it vegetarian with extra veggies.

How to Reheat from Frozen
Best Method (Recommended)
- Transfer to the refrigerator the night before to thaw
- Bake at 350°F for 35 to 40 minutes or until heated through
From Frozen (No Thaw)
- Cover with foil
- Bake at 350°F for 60–75 minutes
- Remove foil during the last 10 minutes to melt and brown the cheese
- 3 ounces Jennie-O Sweet Italian Turkey Sausage, cooked
- 1/4 cup 2% Mozzarella Cheese, shredded
- 1/4 cup Part-Skim Ricotta Cheese
- 1/4 tsp Garlic Powder
- 2 tsp grated Parmesan Cheese
- 1/2 tsp dried Basil
- 1 cup Spaghetti Squash, cooked
- 1/2 cup Great Value Italian diced tomatoes, blended
Step 1: Roast the Spaghetti Squash
Preheat oven to 375°F. Cut the spaghetti squash in half lengthwise and scoop out the seeds. Place on a foil-lined baking sheet, spray with olive oil cooking spray, and season lightly with salt and pepper if desired. Place squash cut side down and bake for about 45 minutes, or until tender. Remove from oven and let cool.
Step 2: Prepare the Squash
Reduce oven temperature to 350°F. Using a fork, scrape the inside of the squash to create spaghetti-like strands. Measure out 1 cup cooked spaghetti squash and place it in the bottom of an oven-safe container.
Step 3: Add Seasoning and Ricotta
Sprinkle the squash with garlic powder and dried basil. Add small spoonfuls of ricotta cheese evenly over the top.
Step 4: Cook the Sausage
Remove the Italian turkey sausage from the casings. Cook in a medium skillet over medium-high heat until fully cooked. Drain any excess fat. Measure out 3 ounces cooked sausage using a food scale.
Step 5: Layer the Lasagna
Add the cooked sausage on top of the ricotta layer. Pour tomato sauce over the sausage. Sprinkle with mozzarella cheese and Parmesan cheese.
Step 6: Bake
Bake at 350°F for 30–35 minutes, or until heated through and cheese is melted.
