How to Make Low Carb Spaghetti Squash Quiche - No Crust, High Protein, So Easy! Recipe
Step 1: Whisk Together Your Wholesome Mixture
Preheat your oven to 375 degrees Fahrenheit. In a large bowl, grab your eggs and whisk them vigorously with the cooked spaghetti squash, Greek yogurt, buffalo sauce, salt, and pepper. This combination forms a creamy, hearty egg base that promises a flavorful bite in every mouthful.
Step 2: Layer Your Flavors in the Baking Dish
Lightly grease a pie pan or baking dish to prevent sticking. Pour your egg and squash mixture in, then sprinkle half of the shredded mozzarella evenly over the top. Distribute the thinly sliced grape tomatoes across the surface, giving each slice space to shine. Finish with the remaining mozzarella for a beautifully melty, golden finish.
Step 3: Bake to Perfection
Pop the dish into the oven and bake for 28 to 32 minutes. You’ll know it’s ready when the center is set firmly (no jiggle) and the edges turn a mesmerizing light golden brown. This baking time ensures every bite is firm yet tender and full of flavor.
Step 4: Cool Before Serving
Once out of the oven, let your quiche cool for 10 to 15 minutes. This step is crucial—it allows the quiche to firm up so when you slice into it, everything holds together neatly without crumbling, making serving a breeze.

Garnishes
A sprinkle of fresh herbs like chives, parsley, or basil adds delightful pops of color and fresh flavor that brighten up this rich dish. You can also offer a drizzle of extra buffalo sauce or a dollop of sour cream for guests who want a little extra tang.
Side Dishes
Because this quiche is low carb and loaded with protein, pairing it with a crisp side salad of mixed greens, cucumbers, and a light vinaigrette makes for a perfectly balanced meal. Roasted asparagus or sautéed spinach are also fantastic veggie options to complement the creamy richness.
Creative Ways to Present
For a brunch party, slice the quiche into mini wedges and serve on colorful plates with individual dollops of Greek yogurt mixed with herbs on the side. You can also turn leftovers into breakfast muffins by portioning the mixture into muffin tins and baking for a grab-and-go option that’s just as satisfying.
Make Ahead and Storage
Storing Leftovers
After enjoying your quiche, wrap any leftovers tightly in plastic wrap or store in an airtight container in the refrigerator. It will stay fresh for up to 4 days, making it a superb ready-to-eat meal any time.

FAQs
Can I use a different type of squash?
While spaghetti squash offers a unique noodle-like texture perfect for this quiche, you can experiment with zucchini or yellow squash shredded and squeezed dry, though it will alter the texture slightly.
Is this recipe suitable for meal prep?
Absolutely! The high protein content and easy storage make it an excellent meal prep option, giving you quick, healthy meals throughout the week.
Can I make this quiche vegan or dairy-free?
This recipe relies heavily on eggs and cheese for structure and flavor, so vegan adaptations would require substitutes like tofu or chickpea flour and dairy-free cheeses, which will change the texture and cooking method.
How spicy is this quiche?
The buffalo sauce adds a gentle heat that livens things up without overpowering. You can adjust the amount to suit your spice preference or swap it for a milder hot sauce if desired.
Can I add other vegetables or proteins?
Definitely! Spinach, mushrooms, cooked bacon, or sausage pieces can be mixed into the egg mixture before baking to customize flavors and make it even heartier.
