This High Protein Quiche (Gluten Free, Low Carb) is a hearty and nutritious dish that brings together rich flavors, creamy textures, and a generous protein boost. Perfect for breakfast, brunch, or a light dinner, this quiche delivers satisfying comfort without relying on traditional high-carb crusts. Every slice offers a balanced combination of eggs, cheese, vegetables, and lean proteins, making it both filling and flavorful.

Whether served warm or at room temperature, this quiche is ideal for meal prep, weekend gatherings, or quick weekday breakfasts. Its custard-like interior and golden top create a dish that feels indulgent, yet aligns with low-carb, gluten-free goals.

Ingredients Overview

The foundation of this quiche begins with eggs, which provide structure, richness, and protein. Combined with cottage cheese and Greek yogurt, they create a creamy, custard-like texture while boosting the protein content, ensuring the dish is filling and wholesome.

Cheese is essential for depth of flavor. Sharp cheddar adds bold, savory notes, while mozzarella contributes meltiness and smoothness. Together, these cheeses create a luxurious, balanced filling.

Vegetables such as spinach, bell peppers, and onions introduce freshness, color, and nutrients. Pre-cooking these ingredients is crucial to remove excess moisture, preventing a soggy quiche.

Lean proteins like turkey sausage, chicken, or smoked salmon make this dish more substantial, turning it into a satisfying main meal.

Instead of a traditional crust, this recipe either uses no crust or incorporates a light almond flour base. This keeps the quiche gluten free and low carb while adding a subtle nutty flavor.

Seasonings such as garlic powder, dried oregano, salt, and black pepper bring all the elements together, enhancing the natural flavors without overpowering them.

Ingredients

6 large eggs
1 cup cottage cheese
1/2 cup plain Greek yogurt
1 cup shredded cheddar cheese
1/2 cup shredded mozzarella cheese
1 cup fresh spinach, chopped
1/2 cup bell peppers, diced
1/3 cup onion, finely chopped
1 cup cooked turkey sausage or diced chicken
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 teaspoon garlic powder
1/2 teaspoon dried oregano
1 tablespoon olive oil
Optional: 1/2 cup almond flour

Step-by-Step Instructions

Preheat the oven to 375°F (190°C) and lightly grease a 9-inch pie dish with olive oil. If using almond flour for a light crust, combine it with olive oil, press into the dish, and bake for 8–10 minutes until lightly golden. Allow it to cool slightly before adding the filling.

Heat a skillet over medium heat and sauté onions and bell peppers in a touch of olive oil until softened, about 3–4 minutes. Add the spinach and cook until just wilted. Let the vegetables cool slightly to avoid adding excess moisture.

In a large bowl, whisk the eggs, cottage cheese, and Greek yogurt until smooth. Fold in shredded cheddar, mozzarella, salt, pepper, garlic powder, and oregano. Mix in the sautéed vegetables and diced protein, ensuring even distribution.

Pour the mixture into the prepared dish and spread evenly. Tap the dish on the counter to release air bubbles. Bake for 35–40 minutes, until the quiche is set in the center and the top is lightly golden. Avoid overbaking to maintain a creamy texture. Let it rest for 10 minutes before slicing for clean portions.

Common errors include adding too-wet vegetables or overcooking, both of which can compromise the texture. Proper preparation and careful baking prevent these issues.

Tips, Variations & Substitutions

This quiche is highly versatile. Swap proteins for cooked bacon, ham, or smoked salmon for different flavor combinations. For a vegetarian version, increase the amount of vegetables, such as mushrooms, zucchini, or broccoli, but ensure they are cooked first to reduce moisture.

For a dairy-free option, substitute plant-based yogurt and cheese alternatives. Nutritional yeast can add a cheesy flavor in place of traditional dairy.

Adjust the custard consistency by modifying yogurt amounts—more yogurt or cottage cheese creates a softer, creamier quiche, while less produces a firmer texture. Fresh herbs like chives, parsley, or basil can be added before baking to enhance flavor.

Serving Ideas & Occasions

High Protein Quiche (Gluten Free, Low Carb) is ideal for any mealtime. Serve it with a crisp salad, avocado slices, or roasted vegetables for lunch or dinner. For breakfast or brunch, pair it with fresh fruit or a smoothie.

It works well for meal prep or family gatherings, as it holds its shape and flavor even after refrigeration. The quiche can be served warm, at room temperature, or chilled, making it a flexible and convenient option.

Nutritional & Health Notes

This quiche is packed with protein and balanced nutrients. Eggs, cottage cheese, and Greek yogurt provide high-quality protein and calcium, while vegetables supply fiber, vitamins, and minerals. Using a crustless or almond flour base keeps the carb content low.

Portion control is important due to the richness of the cheese and protein. The combination of protein, healthy fats, and vegetables makes it a well-rounded, nutrient-dense meal suitable for low-carb lifestyles.

FAQs

Can I make this quiche ahead of time?

Yes. Bake and cool the quiche, then store it in the refrigerator for up to four days. Reheat slices in the oven or microwave when ready to eat. Preparing ahead allows flavors to meld and saves time on busy mornings.

How do I avoid a watery quiche?

Cook vegetables thoroughly before adding them to release excess water. Spinach, mushrooms, and zucchini are especially high in moisture. Letting the quiche rest after baking helps it set and prevents a watery texture.

Is freezing possible?

Yes, fully baked quiche freezes well. Cool completely, wrap slices individually or store the whole quiche in an airtight container, and freeze for up to two months. Thaw in the refrigerator overnight and reheat in the oven. Texture may change slightly, but flavor remains intact.

What cheeses are best?

Cheddar and mozzarella work well together. Cheddar provides bold flavor, while mozzarella contributes melt and smoothness. Swiss or feta can be substituted depending on taste. Choose cheeses that melt evenly for best results.

Can I make it dairy-free?

Yes, by using plant-based alternatives for cheese and yogurt. The texture may differ slightly, but adding nutritional yeast can mimic a cheesy flavor. Use unsweetened, plain substitutes to maintain the savory profile.

How do I know it’s fully cooked?

The center should be set but slightly soft, and the top should be lightly golden. Insert a knife; it should come out mostly clean. Overbaking can lead to a dense, rubbery texture. Resting after baking helps maintain structure.

Is a crust necessary?

No, a crustless version works perfectly and reduces carbs. Greasing the dish ensures the quiche holds together and slices cleanly. A light almond flour base can be added for texture if desired.
