How to Make Healthy Spaghetti Squash Au Gratin

Step 1: Preheat Your Oven

Start by preheating your oven to 400°F (205°C). This ensures it’s nice and hot when you’re ready to roast the spaghetti squash, allowing it to caramelize beautifully.

Step 2: Roast the Squash

Slice the spaghetti squash in half lengthwise and scoop out those seeds. Brush the cut sides with olive oil and place them face-down on a baking sheet. Roast for about 35–40 minutes until tender. This roasting method brings out the natural sweetness of the squash!

Step 3: Sauté Onions and Garlic

While your squash roasts, heat a skillet over medium heat. Sauté diced onions in a bit of olive oil until they soften—about five minutes should do it! Add minced garlic for just another minute. This step builds flavor by bringing out their natural sweetness.

Step 4: Shred the Squash

Once your roasted squash has cooled enough to handle, use a fork to shred it into noodle-like strands. This is where that fun spaghetti texture comes from!

Step 5: Mix It All Together

In a large bowl, combine your shredded squash with sautéed onions and garlic, Greek yogurt, one cup of cheese, salt, pepper, and optional spices if you’re using them. Mix everything together well; this helps distribute those lovely flavors throughout.

Step 6: Bake It Up

Transfer your mix into a greased casserole dish and sprinkle the remaining half-cup of cheese on top. Bake at 375°F (190°C) for 20–25 minutes until it’s hot and bubbly with that beautiful golden crust on top.

Step 7: Serve & Enjoy!

Let your Healthy Spaghetti Squash Au Gratin cool slightly before digging in. It’s perfect as a side dish or light main course—enjoy every bite!

Pro Tips for Making Healthy Spaghetti Squash Au Gratin

Creating a perfect Healthy Spaghetti Squash Au Gratin is easier than you might think! Here are some pro tips to ensure your dish turns out beautifully every time.

• Choose a ripe squash: Look for a spaghetti squash that feels heavy for its size and has a firm skin. This indicates ripeness and ensures better flavor and texture.

• Don’t rush the roasting: Roasting the spaghetti squash until it’s tender is key. If it’s undercooked, the strands won’t separate properly, impacting the final dish’s texture.

• Experiment with cheese: While sharp cheddar adds great flavor, feel free to mix in other cheeses like mozzarella or gouda for a different twist. This can enhance creaminess and richness.

• Make it ahead of time: You can prepare the mixture a day in advance and store it in the refrigerator. Just bake it right before serving to save time on busy nights!

• Adjust seasoning to taste: Don’t hesitate to tweak the salt, pepper, or herbs according to your preferences. Everyone’s palate is different, so make it yours!

Side Dishes

• Garlic Green Beans: Sautéed green beans with garlic and olive oil are simple yet flavorful. They add a crunchy contrast to the creamy gratin.
