Is Spaghetti Squash Low Carb?
Yes, spaghetti squash is considered low in carbs, making it a popular choice for those following a keto or low-carb diet. One cup (about 155 grams) of cooked spaghetti squash contains approximately 7 grams of total carbs, with around 2 grams of fiber, resulting in 5 grams of net carbs. It's a great alternative to traditional pasta, offering a similar texture with significantly fewer carbs, while also providing vitamins and minerals like vitamin C, B vitamins, and potassium.
Ingredients
- Spaghetti Squash - Is cooked first before mixing into the other ingredients for the casserole.
- Cooked chicken or beef - Any protein of your choice can be used.
- Mozzarella cheese - Mozzarella gives the casserole a gooey, cheesy topping, making each bite rich and satisfying. It’s a key ingredient in creating that classic pizza taste.
- Parmesan cheese - Parmesan adds a slightly nutty flavor and a layer of depth to the casserole. It helps to enhance the overall cheesiness of the dish.
- Marinara sauce - Choose a low-carb marinara or pizza sauce to keep this dish keto-friendly. The sauce adds classic tomato flavor and binds the ingredients together.
- Onion - The onion adds sweetness and depth to the casserole
- Garlic - Brings an aromatic, savory note that complements the tomato sauce and cheese.
- Italian Seasoning - A blend of herbs like basil, oregano, and thyme that infuses the dish with classic Italian flavors.
How to Make Spaghetti Squash Pizza Casserole
This casserole can be made a day in advance. Simply prepare it, cover, and refrigerate. When you're ready to bake, add an extra 5-10 minutes to the cooking time.
Cut squash in half, remove seeds and cook.
Scrape out the squash strands with a fork.
Cook onion, garlic and add the cooked chicken (or beef)
Add marinara sauce, seasoning and cheese.
Mix in the spaghetti squash.
Spoon into casserole dish, top with cheese and your favorite pizza toppings and bake.
Recipe Tips
Spaghetti squash can release water as it cooks, making the casserole watery. To avoid this, place the cooked squash strands on paper towels and pat them dry before mixing them with the sauce and cheese.
Choose for full-fat mozzarella and Parmesan for better melting and flavor. Low-fat versions may not melt as well and can make the dish less creamy.
For more flavor and texture, consider adding extra low-carb veggies like mushrooms, spinach, or zucchini. Sauté them with the onions and garlic before adding to the casserole.
Feel free to get creative with the toppings. Try bacon, ham, different types of cheese, or even jalapeños for a spicy kick.
Storing Leftovers
Transfer leftovers to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Store in the refrigerator for up to 3-4 days.
Freezing
For longer storage, portion the casserole into individual servings and place them in freezer-safe containers or wrap tightly in plastic wrap followed by aluminum foil. Freeze for up to 2-3 months. Thaw in the refrigerator overnight before reheating.
Reheating
Oven: Reheat in a preheated 350°F (175°C) oven for about 15-20 minutes, or until heated through.
Microwave: For quicker reheating, microwave individual portions on medium power for 2-3 minutes, or until hot.
