Ingredients
Gather ’round, let’s look at the simple stars of our show:
- 1 medium Spaghetti squash: This is our amazing stand-in for pasta or potatoes. When roasted, the inside shreds into noodle-like strands!
- 2 cloves Garlic: Because everything is better with garlic, right? Mince ’em up!
- 1/2 cup Onion: Just a little bit, finely chopped, to add a layer of savory flavor.
- 1 tbsp Olive oil: For sautéing our aromatics and helping the squash roast.
- 1 1/2 cups Sharp cheddar cheese: The heart of our cheesy delight! Sharp gives you the most bang for your buck in terms of flavor. Shred it yourself if you can – it melts better!
- 1/2 cup Plain Greek yogurt: Here’s our secret ingredient for creaminess and a protein boost without heavy cream or butter. Make sure it’s plain and unsweetened!
- 1/4 tsp Salt: Just enough to enhance all those lovely flavors.
- 1/4 tsp Black pepper: A little warmth and spice.
How to Make It
Alright, let’s get cooking! It’s way easier than you might think.
- Prep the Squash: First things first, we need to tackle that spaghetti squash. Preheat your oven to 400°F (200°C). Carefully (seriously, be careful!) cut the squash in half lengthwise. Scoop out the seeds and stringy bits with a spoon. You can rub the cut sides with a little olive oil and a pinch of salt and pepper, or just place them cut-side down on a baking sheet.
- Roast the Squash: Pop the squash into the preheated oven. Roast for about 40-50 minutes, or until it’s tender when you poke the skin with a fork. Roasting time varies a lot depending on the size of your squash! Let it cool just enough so you can handle it.
- Shred the Squash: Once cool enough, use a fork to gently scrape the flesh away from the skin. It will naturally shred into those lovely spaghetti-like strands. Place the squash strands in a large bowl.
- Sauté the Aromatics: While the squash is cooling slightly, heat the olive oil in a small skillet over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. Don’t let the garlic burn!
- Mix the Magic: Add the cooked onion and garlic to the bowl with the spaghetti squash. Now, add your shredded cheddar cheese (reserve a little bit for topping if you like!), the plain Greek yogurt, salt, and pepper. Gently mix everything together until the squash is coated in the creamy, cheesy mixture.
- Assemble and Bake: Pour the mixture into a medium-sized baking dish (an 8×8 inch or similar sized dish works great). If you saved some cheese, sprinkle it over the top.
- Bake Again!: Place the dish back into the 400°F (200°C) oven and bake for 15-20 minutes, or until the cheese is melted, bubbly, and slightly golden on top.
- Rest and Serve: Let the au gratin sit for just a few minutes before serving. This helps it set slightly. Dish it up and enjoy that cheesy, comforting goodness!
Substitutions & Additions
Want to get creative? This recipe is super flexible!
- Cheese Swap: Gruyere, white cheddar, or even a blend of cheeses would be delicious instead of sharp cheddar.
- Yogurt Alternative: Full-fat plain Greek yogurt gives the best texture and richness, but you could try lower-fat if needed. Regular plain yogurt might be too thin. A bit of cream cheese or even a splash of milk could be used for creaminess, but the yogurt adds that healthy tang.
- Add Veggies: Sautéed spinach, broccoli florets, mushrooms, or bell peppers would be fantastic additions. Add them when you sauté the onion and garlic, or stir in pre-cooked veggies with the squash.
- Boost Protein: Stir in some cooked chopped chicken, ham, or crispy bacon bits for a heartier meal.
- Spice It Up: A pinch of red pepper flakes in the sauté or stirred into the mix gives it a nice kick.
- Breadcrumbs: For extra texture, sprinkle some panko breadcrumbs mixed with a tiny bit of melted butter over the top before the final bake.
Tips for Success
Making this dish is pretty straightforward, but here are a few little pointers I’ve picked up:
- Dealing with Watery Squash: Spaghetti squash can sometimes hold a lot of water. After shredding, you can gently press it in a fine-mesh sieve or blot it with paper towels to remove excess moisture before mixing. This prevents your au gratin from being watery.
- Cutting the Squash Safely: Squash can be tough to cut. A sharp knife is key! You can also poke it all over with a fork and microwave it for 3-5 minutes before cutting to soften it slightly.
- Don’t Over-Roast: If you roast the squash for too long, it can get mushy instead of forming nice strands. Check it around the 40-minute mark.
- Prep Ahead: You can roast and shred the spaghetti squash a day or two in advance and store it in the fridge. Then, when you’re ready to eat, just do the quick sauté, mix everything together, and bake!
How to Store It
Got leftovers? Lucky you! This Healthy Spaghetti Squash Au Gratin stores beautifully.
- Fridge: Let the dish cool completely, then cover it tightly with plastic wrap or transfer it to an airtight container. It will keep in the refrigerator for 3-4 days.
- Reheating: You can reheat individual portions in the microwave. For a larger amount, cover it loosely with foil and warm in a 325°F (160°C) oven until heated through.
- Freezing: I don’t typically freeze this dish as the texture of the squash can change a bit upon thawing, sometimes becoming more watery. It’s best enjoyed fresh or from the fridge.
FAQs
Got questions? Let’s see if I can help!
Is this dish gluten-free?
Yep! Since it uses spaghetti squash instead of pasta or breadcrumbs (unless you add them!), this recipe is naturally gluten-free.
Can I use pre-shredded cheese?
You can, but block cheese that you shred yourself usually melts more smoothly because it doesn’t contain the anti-caking agents found in some pre-shredded varieties.
Does it really taste like mac and cheese or potato au gratin?
It won’t exactly replicate them – spaghetti squash has its own unique, mild flavor and texture. But it captures that same spirit of creamy, cheesy, baked comfort food in a delicious, veggie-packed way!
Can I make this dairy-free?
It would require quite a few substitutions. You’d need a good plant-based cheese alternative that melts well and a dairy-free plain yogurt or cream cheese substitute. It might work, but the flavor and texture would definitely be different from the original recipe.
I hope you love this Healthy Spaghetti Squash Au Gratin as much as my family and I do! It’s proof that comfort food can be both delicious and nutritious. Happy cooking!
