How to Make Healthy Spaghetti Squash Au Gratin

Step 1: Roast the Spaghetti Squash

Preheat your oven to 400°F (205°C). Start by slicing the spaghetti squash in half lengthwise and scooping out the seeds. Roasting brings out its natural sweetness and makes it tender. Brush the cut sides with olive oil before placing them face-down on a baking sheet. Roast for about 35–40 minutes until you can easily pierce it with a fork.

Step 2: Sauté Onions and Garlic

While your squash is roasting, let’s get those onions cooking! Heat a skillet over medium heat and sauté the diced onions in a bit of olive oil until they become soft—about 5 minutes will do. Adding minced garlic at this stage gives off such an inviting aroma; cook just until fragrant (about another minute) before taking them off the heat. This step enhances their sweetness and adds depth to our casserole.

Step 3: Shred the Squash

Once your roasted squash has cooled enough to handle, grab a fork and shred it into noodle-like strands. This is where the magic happens! The texture mimics traditional pasta but keeps things light and healthy.

Step 4: Combine Ingredients

In a large mixing bowl, combine your shredded squash with sautéed onions, garlic, Greek yogurt (or sour cream), one cup of shredded cheese, salt, pepper, and any optional spices like paprika or thyme. Mix well; every bite should be full of flavor!

Step 5: Bake It Up!

Transfer your mixture into a greased casserole dish and sprinkle the remaining half cup of cheese on top. Bake at 375°F for about 20–25 minutes until everything is hot and bubbly with a lovely golden top.

Step 6: Serve & Enjoy!

Let your Healthy Spaghetti Squash Au Gratin cool slightly before serving. Scoop out portions as a side dish or enjoy it as a light main course—either way, it’s sure to impress!

Pro Tips for Making Healthy Spaghetti Squash Au Gratin

Creating the perfect Healthy Spaghetti Squash Au Gratin is a delightful experience, and with these handy tips, you’ll ensure it turns out just right!

• Choose the right squash: Selecting a firm, unblemished spaghetti squash will yield the best texture and flavor. A ripe squash has a slightly dull skin and feels heavy for its size.

• Roast until golden: When roasting your spaghetti squash, let it get a bit caramelized. This enhances the natural sweetness of the squash and adds depth to your dish.

• Experiment with cheeses: While sharp cheddar is delicious, feel free to mix in other cheeses like mozzarella or pepper jack for added creaminess and flavor complexity.

• Customize with veggies: Don’t hesitate to add in some extra veggies! Spinach, bell peppers, or even mushrooms can complement the flavors beautifully and increase the nutritional value.

• Rest before serving: Allow your au gratin to sit for about 5 minutes after baking. This helps it set up nicely and makes serving easier while enhancing the flavors.

Side Dishes

• Simple Green Salad: A refreshing green salad with mixed greens, cherry tomatoes, and a light vinaigrette complements the richness of the au gratin perfectly.

• Garlic Roasted Broccoli: Toss broccoli florets in olive oil, garlic, salt, and pepper, then roast until tender. This side adds a nutritious crunch that balances well with the creamy gratin.
