Craving Comfort: Low Carb Spinach and Feta Quiche Recipe
Quiche might seem keto-friendly at first glance—eggs, cheese, veggies—but that buttery crust quickly eats up your carb allowance. Rude, right?
This Low Carb Spinach and Feta Quiche delivers all the creamy, savory comfort you want, skipping the carb-heavy crust—opt for crustless (my go-to for weeknights) or a simple keto crust if you want a sliceable brunch treat.
Why This Recipe Matters for Keto
This quiche nails the keto essentials: high protein, satisfying fats, and low carbs, without tasting like diet food. It’s cozy enough for Sunday brunch and practical enough to save you from the “what else besides bacon?” dilemma.
Plus, it’s perfect for real life:
- Enjoy hot, warm, or straight from the fridge (no judgment!)
- Easy to meal prep
- Flexible with add-ins depending on what your fridge holds
Why This Recipe Works for Keto
Traditional quiche depends on the crust, but keto quiche focuses on the rich, custardy filling we really crave.
By eliminating the flour-based shell or swapping in a keto crust, carbs stay low while eggs and cheese create an indulgent flavor that fits your macros.
Low Carb Essentials Powering This Dish
- Eggs: Provide structure, protein, and that filling custard texture that holds the quiche together.
- Feta Cheese: Salty, tangy flavor that makes spinach shine.
- Spinach: Adds nutrients and volume with minimal carbs, preventing the quiche from feeling overly cheesy.
Flavor, Texture, and Satisfaction
Even without a traditional crust, you get the classic quiche appeal: creamy, silky interior with bursts of salty feta and mellow, earthy spinach.
Pro tip: water is the enemy of perfect quiche texture. Spinach holds moisture, so drying it thoroughly (think squeezing with towels) is key to avoid a soggy outcome.
Comparing to Non-Keto Versions
Regular quiches rely on flour crusts and sometimes richer dairy bases, making the filling secondary. This version flips that — no crust carbs and the filling shines. Most people don’t miss the pastry once they taste the rich custard inside.
Is it traditional? No. Is it keto and delicious? Absolutely.
Tips for Success
Cooking Tips That Matter
- Use fresh spinach whenever possible. It cooks fast and tastes better. If frozen, thaw fully and squeeze out moisture thoroughly.
- If using a keto crust, pre-bake it. This prevents soggy bottoms and keeps textures spot on.
- Don’t overbake. Remove when the center is just slightly jiggly. It will firm up while cooling, giving that creamy custard texture instead of dry eggs.
Substitutions and Variations
- Cheese swaps:
- Goat cheese for tangier creaminess
- Swiss for mild, classic flavors
- Mozzarella if you prefer mellow; add extra seasoning
- Add-ins (watch carbs):
- Mushrooms (cook first to release moisture)
- Diced onions (sparingly)
- Cherry tomatoes (small amounts)

Low Carb Spinach and Feta Quiche
Equipment
- 10 inch pie dish
- large skillet
- Mixing bowl
- Whisk
- Colander or strainer
- clean kitchen towels
- measuring cups and spoons
- Oven
Ingredients
For the quiche filling
- 8 large eggs
- 3/4 cup heavy whipping cream full-fat
- 1/4 cup unsweetened almond milk
- 1 cup crumbled feta cheese
- 1 cup shredded mozzarella cheese low-moisture, part-skim
- 5 cups fresh baby spinach loosely packed
- 2 tablespoons unsalted butter
- 1/4 cup finely chopped yellow onion use sparingly to keep carbs low
- 2 cloves garlic minced
- 1/2 teaspoon fine sea salt plus more to taste
- 1/4 teaspoon freshly ground black pepper
- 1/4 teaspoon dried oregano
- 1/8 teaspoon crushed red pepper flakes optional, for a mild kick
For preparing the dish
- 1 tablespoon olive oil for greasing the pie dish
Instructions
- Preheat the oven to 350°F and grease a 10 inch pie dish with olive oil, making sure the bottom and sides are well coated.
- Heat a large skillet over medium heat and melt the butter until it just begins to foam.
- Add the chopped onion to the skillet and cook, stirring occasionally, until softened and translucent, about 3 to 4 minutes.
- Stir in the minced garlic and cook until fragrant, about 30 seconds, being careful not to let it brown.
- Add the fresh spinach to the skillet in batches, stirring frequently, until all of the spinach is wilted and most of the moisture has evaporated.
- Transfer the cooked spinach mixture to a colander and let it cool slightly, then use clean kitchen towels to squeeze out as much excess water as possible so the quiche is not watery.
- Spread the well dried spinach mixture evenly over the bottom of the prepared pie dish and sprinkle the crumbled feta and shredded mozzarella evenly over the spinach.
- In a large mixing bowl whisk together the eggs, heavy whipping cream, and unsweetened almond milk until the mixture is smooth and well combined.
- Season the egg mixture with salt, black pepper, dried oregano, and red pepper flakes if using, and whisk again to distribute the seasonings evenly.
- Pour the seasoned egg and cream mixture slowly over the spinach and cheese in the pie dish, tapping the dish gently on the counter so the custard settles and fills any gaps.
- Place the pie dish on the center rack of the preheated oven and bake until the edges are set and the center is just slightly jiggly when the dish is gently shaken, about 30 to 35 minutes.
- Remove the quiche from the oven and let it rest on a cooling rack for at least 10 minutes to allow the custard to finish setting and to make slicing easier.
- Slice the quiche into wedges and serve warm, or let it cool completely and refrigerate for quick keto breakfasts, lunches, or snacks throughout the week.
