Spaghetti Squash Casserole: Loaded with Nutrients

Spaghetti squash casserole - Dr. Axe

Eating seasonally is one of the best parts about home cooking. And when autumn and winter hits, warm, comforting casseroles fit the bill.

Too often, though, casseroles are recipes packed with heavy, refined carbs and few, if any, vegetables. While they may taste good, you won’t feel too great after a serving. That’s what makes this healthy spaghetti squash casserole such a stellar cold-weather meal.

Here, spaghetti squash replaces the pasta you typically find in casseroles. You’ll add a colorful medley of vegetables, but with both mozzarella and raw goat cheese, this easy-to-make spaghetti squash casserole feels indulgent — it’s the best of both worlds!

Key Ingredients

The key ingredient to this casserole is the spaghetti squash. At first glance, this vegetable doesn’t resemble anything close to spaghetti. But once the squash is cooked, its flesh turns to spaghetti-like strands, perfect for sauces, casseroles or any other meal where pasta is normally used.

Best of all, spaghetti sauces is packed with nutrients you just won’t find in pasta. Its bright hue is thanks to the beta-carotene. This cartenoid is one of the reasons why spaghetti squash is full of antioxidants and great for your skin, eyes and respiratory health.

But spaghetti squash isn’t the only good-for-you ingredient in this healthy casserole. You’ll also include two of the healthiest leafy greens: kale and spinach.

Kale is an impressive anti-inflammatory food. Because it’s full of omega-3s, it helps balance our omega-3 to omega-6 ratio, critical for keeping inflammation at bay. It’s also great for heart health and helping to lower cholesterol and promote cellular health.

Spinach is another green nutrition giant. It helps guard cells from mutations that lead to cancerous tumor growth and protects against heart disease. The fiber found in spinach both slows the blood’s absorption of glucose and reduces cholesterol levels, two important factors in reducing your risk of a heart attack or stroke.

The high levels of vitamins A and C also boost immunity, helping you keep bacteria and viruses at bay. The average casserole recipe cannot do that.

    I have heard that putting acidic foods, like tomatoes, in cast iron is not a good thing–I made this in a glass casserole dish as an alternative.

    Best vegetarian dish ever, and the left overs are even better. I am not. Vegetarian of GF, but I have sensitivities to the bad stuff. 3 years ago my son was diagnosed with autism and I suspect that I am autistic too, since then a lot of changes in my life. Thank you for share your knowledge and this wonderful receipt.

    So you used nightshades, FULL OF LECTINS, and unless they are pressure-cooked, cause leaky gut.

    “4. Nightshades – Nightshades are vegetables that include eggplant, any kind of pepper, potatoes, and tomatoes. The peels and the seeds of these plants contain loads of lectins, too. Make sure to peel and deseed them or pressure cook or ferment them. All these techniques reduce the amount of lectins.” Gundry

    Hi,
    I just prepared this dish tonight. I forgot to buy the kale, so I added an extra cup of spinach. I also used 1/2 sweet yellow onion as I am sensitive to other onions. Also topped it with some black olives and the basil I used was fresh picked from my garden. I love the Fall season and eating the squash and other veggies that are fresh and ripe now!
    This was absolutely delish! Thank you, Dr. Axe, for sharing this amazing recipe- I give it 5 stars!
    Blessings :)
