Southwest Spaghetti Squash Casserole Recipe FAQs
How do I choose a good spaghetti squash?
When selecting a spaghetti squash, look for one that is firm and free of soft spots or blemishes. The skin should be a vibrant yellow-orange color. A good-sized squash typically weighs between 3 to 5 pounds. If it feels heavy for its size, that’s a great sign that it’s full of delicious strands inside!
How should I store leftover spaghetti squash casserole?
Leftover spaghetti squash casserole can be stored in an airtight container in the fridge for up to 4 days. Make sure it’s completely cooled before sealing to maintain its flavor and texture. To reheat, simply microwave individual portions for 2-3 minutes or bake at 350°F (175°C) until warmed through.
Can I freeze spaghetti squash casserole?
While it’s not recommended to freeze spaghetti squash casserole due to potential texture changes in the squash, it can be done if needed. Use a freezer-safe container and make sure to consume it within 1 month. To thaw, leave it in the fridge overnight, and reheat in the oven or microwave until heated through.
What can I do if my casserole turns out too watery?
If your casserole is too watery, it may be due to excess moisture in the spaghetti squash or other ingredients. To fix it, consider draining the liquid before serving. Additionally, try adding a thickening agent like corn starch mixed with a bit of water and stir it into the casserole while it’s heating up. For future recipes, roasting the squash until it’s completely tender will help reduce moisture.
Is this casserole safe for my gluten-free friends?
Absolutely! This Southwest Spaghetti Squash Casserole is naturally gluten-free as it uses spaghetti squash in place of traditional pasta. However, always check labels on any sauces or canned goods you use (like the enchilada sauce) to ensure they are also gluten-free.
Can I make a vegetarian version of this casserole?
Very much so! To make a vegetarian version of the spaghetti squash casserole, simply omit the chicken and double the amount of black beans.
