Ingredients for 10 egg frittata
Ten eggs and twelve versatile ingredients create a brunch masterpiece for six hungry guests.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 10 whole | Room temperature for even cooking |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality for crispy crust |
| Shallots 🧅 | 2 whole | Finely diced for sweetness |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic depth |
| Bell Peppers 🌶️ | 2 whole | Assorted colors, diced |
| Red Onion 🧅 | 1 whole | Thinly sliced for caramelization |
| Spinach 🌿 | 5 oz | Fresh, roughly chopped |
| Shredded Gruyère Cheese 🧀 | 2 cups | Aged for nutty flavor |
| Heavy Cream 🥛 | ¼ cup | For luxurious texture |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Nutritional Yeast 🍄 | 2 tbsp | For umami depth (optional) |
The eggs are the foundation—use room temperature ones for even cooking. Whole eggs ensure a rich, custardy texture, while the extra-virgin olive oil (look for California Early Harvest or Colavita for optimal flavor) creates that coveted crispy crust. Shallots and garlic should be freshly minced—no pre-chopped mixes here. The Gruyère is non-negotiable; its melting properties and nutty depth elevate every bite. For the cheese, Whole Foods Market or specialty cheese shops offer the best quality, but pre-shredded works in a pinch if labeled 'block-style' to avoid clumping. The spinach should be fresh—wilting leaves release bitterness, so buy it the day you cook.
No shallots? Substitute with extra finely diced red onion—just add a pinch more salt to balance. Swap bell peppers for zucchini or mushrooms if you prefer earthier notes. The heavy cream can be reduced to half-and-half for a lighter texture, though purists will argue it's worth the richness. For a dairy-free option, full-fat coconut milk mimics the creaminess surprisingly well. Nutritional yeast isn't mandatory but adds that cheesy umami without dairy—Bob's Red Mill is a reliable brand. If your frittata needs extra moisture, add 2 oz of sautéed onions or a splash of milk. And for heaven's sake, don't skip the whisking—those eggs need to be thoroughly combined for that silky texture.
Prep the vegetables first—they'll release moisture while you whisk the eggs. Store any prepped veggies in an airtight container in the fridge for up to 24 hours before cooking. The cheese should be kept in its original packaging or a sealed container to prevent drying out. This frittata reheats beautifully—350°F for 10-15 minutes restores that warm, gooey center. For meal prep, slice into wedges and freeze portions in a single layer before transferring to a bag. They'll keep up to 3 months frozen, though texture may soften slightly. Serve immediately for that restaurant-quality presentation—golden crust, creamy interior, and all.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this—no dirty pots, just one skillet, and you’re done. The olive oil caramelizes those shallots and garlic until they’re golden, then the eggs bind everything into a single, satisfying dish.
- Caramelized Crisp: That crispy bottom layer? It’s the secret weapon. Sauté the bell peppers until they’re soft but still bright, then pour in the eggs—when they set, you get this perfect contrast of tender and crispy. Honestly, it’s the kind of texture that makes you pause mid-bite.
- Meal Prep MVP: Between us, this is my go-to for lunches all week. Cook a big batch on Sunday, slice it up, and reheat portions in minutes. The eggs stay moist, the veggies don’t turn mushy, and it’s always a hit—even with picky eaters.
- Budget Breakthrough: Ten eggs for one meal? Yes, please. It stretches a grocery trip further than scrambled eggs ever could, and the veggies add freshness without breaking the bank. Plus, leftovers taste just as good cold the next day.
Step-by-step instructions for a 10-Egg frittata
Master this one-pan technique for a perfectly balanced frittata with rich texture and deep flavor.
Sauté the Vegetable Base
Heat the 0.5 cup extra-virgin olive oil in a 12-inch oven-safe skillet over medium-high heat. Add the finely diced 2 whole shallots and cook for 3-4 minutes until they soften and begin to caramelize. This foundational step builds sweetness that carries through the entire dish.
Add the thinly sliced 1 whole red onion and cook for another 4-5 minutes until translucent. Stir in the minced 4 cloves garlic and cook for 30 seconds until fragrant—this prevents the garlic from burning while maximizing its aromatic potential. Remove the skillet from heat temporarily and set aside.
Prepare the Egg Mixture
In a large bowl, whisk together the 10 whole large eggs (at room temperature) with the 0.25 cup heavy cream until fully combined. Add the 1.5 teaspoons kosher salt, 0.5 teaspoon freshly ground black pepper, and 2 tablespoons nutritional yeast, whisking until evenly distributed. The nutritional yeast adds a subtle umami depth that complements the Gruyère beautifully.
Fold in half of the 2 cups shredded Gruyère cheese (reserve the rest for topping) and half of the 5 oz spinach. The spinach will wilt slightly as it incorporates into the egg mixture, creating pockets of vibrant green throughout the frittata. Let the mixture sit for 2-3 minutes while you finish prepping the remaining ingredients.
Layer and Cook the Frittata
Return the skillet to medium heat and add the diced 2 whole bell peppers to the sautéed vegetables. Cook for 5-6 minutes until the peppers soften but retain their shape. Pour the egg mixture evenly over the vegetables, spreading it into an even layer with a spatula. Immediately sprinkle the remaining 1 cup shredded Gruyère cheese and remaining 2.5 oz spinach over the top.
Reduce heat to low and let the frittata cook undisturbed for 8-10 minutes. You'll see the edges begin to set while the center remains slightly custardy—this is ideal. The low heat allows gentle cooking that prevents the eggs from curdling while developing a golden crust around the edges.
Finish in the Oven for Perfect Texture
Transfer the skillet to a preheated 375°F oven and bake for 12-15 minutes. The frittata is ready when the top is golden brown and the center is just set—it should still have a slight jiggle when gently shaken. This oven finish ensures even cooking throughout without overbrowning the top.
For a final touch, broil for 1-2 minutes to achieve a beautifully browned crust. Watch closely to prevent burning. Remove from the oven and let rest for 5 minutes before slicing—this resting period allows the internal structure to firm up, making clean slices possible.
Pro Tips For Making 10 Egg Frittata
- CRANK HEAT TO SEAR: Start your frittata on medium-high heat—no, really, crank it up. I used to play it safe with medium, and my eggs turned out soft and sad. A hot pan gets those shallots and bell peppers caramelizing in 3-4 minutes, building flavor before the eggs even hit the pan. (Yes, even if you're impatient like me.)
- CHOP SHALLOTS SMALL: Tiny dice, not slices. I learned this the hard way after my first frittata had chewy shallot chunks that didn’t soften. Aim for 1/8-inch pieces—they’ll melt into the eggs instead of sitting like awkward guests. Same goes for garlic: minced, not chopped.
- STIR ONCE, THEN LET IT BE: After adding the beaten eggs, give one gentle stir with a spatula—just to distribute the shallots and peppers. Then walk away. I used to obsess over stirring, and my frittatas ended up dense. Let the eggs set undisturbed for 2-3 minutes before poking at them again.
- USE COLD EGGS: Pull them straight from the fridge—no pre-beating at room temp. Cold eggs whip up fluffier and hold their shape better, especially in a 10-egg batch. (I know it’s tempting to speed things up, but trust the process.)
Make-ahead tips for this 10 egg frittata
Prep Ahead Basics
Start by prepping all your vegetables the night before. Dice the 2 whole shallots, 1 whole red onion, and 2 whole bell peppers, then store them in an airtight container in the fridge.
This saves you 15-20 minutes of prep time the next morning. I like to add a pinch of salt to the veggies to draw out excess moisture, which prevents a soggy frittata. 🌶️
Egg Mixture Prep
Whisk the 10 eggs with 0.25 cup heavy cream, 1.5 tsp kosher salt, and 0.5 tsp black pepper in advance and store in the fridge. The nutritional yeast can be mixed in right before cooking.
This prepped mixture stays fresh for up to 24 hours, making it perfect for lazy weekend mornings. Just pop it in the oven after sautéing your veggies!
Cheese Storage Tips
Shred the 2 cups Gruyère cheese and store it in a sealed container with a piece of parchment paper to prevent clumping. The cheese can stay in the fridge for 3 days before the frittata.
For extra convenience, portion the cheese into 2 separate bags: one for mixing into the eggs and one for topping. This keeps your morning routine smooth and stress-free. 🧀
Freezing for Later
Frittatas freeze beautifully! Let your fully cooked frittata cool completely, then slice into wedges. Place them in a single layer on a baking sheet, freeze for 1 hour, then transfer to a freezer bag with parchment between layers.
They’ll keep for up to 3 months. To reheat, bake at 350°F for 15-20 minutes until warmed through. The texture stays creamy, not rubbery. 💫
Morning Assembly
On the day of cooking, simply reheat your prepped veggies in the skillet for 3-4 minutes, then pour in the pre-whisked egg mixture. The 5 oz spinach can be added fresh or pre-wilted—either way, it’ll blend perfectly.
This 5-minute assembly turns your frittata into a stress-free brunch staple. Perfect for busy mornings when you still want a gourmet meal! ⏰
Reheating Leftovers
Reheat individual slices in a non-stick skillet over medium-low heat for 2-3 minutes per side until warmed through. For a quick fix, microwave on 50% power for 45 seconds, then cover with a damp paper towel to retain moisture.
The Gruyère melts beautifully, making even leftovers taste fresh. Store leftovers in the fridge for up to 4 days in an airtight container.

Frequently asked questions
Can I make this frittata in a smaller pan?
Yes, but you'll need to adjust the recipe. A 9-inch skillet works well for a 6-egg frittata—simply halve the ingredients. For a 10-inch pan, you can use the full recipe as-is. The key is maintaining a 1-inch thick layer of egg mixture for even cooking. If your pan is too small, cook in batches or use a smaller skillet for a mini frittata!
Why did my frittata turn out rubbery?
Overcooking is the most common cause. The center should have a slight jiggle when done—like 215°F custard. Use an instant-read thermometer to check the internal temp. Also, ensure your eggs are fully whisked and the heat is low when cooking on the stovetop. High heat causes the proteins to tighten too quickly, creating that rubbery texture.
How do I add meat to this vegetarian recipe?
Cook your protein (like diced ham or sausage) separately until fully done, then drain excess fat before adding to the sautéed vegetables. For a 10-egg frittata, use ½ pound of meat—it should be about 1 cup cooked. Fold it into the egg mixture along with the cheese. Avoid overly greasy meats like bacon, as they can make the frittata soggy.
Can I make this frittata ahead and reheat?
This frittata reheats beautifully. Store leftovers in an airtight container for up to 4 days. To reheat, bake at 350°F for 10-15 minutes or warm slices in a skillet over medium-low heat for 2-3 minutes per side. For microwave reheating, use 50% power for 45 seconds and cover with a damp paper towel to retain moisture.
What’s the best way to serve this frittata?
Slice into 6-8 wedges for easy serving. Pair with a fresh arugula salad (tossed with lemon vinaigrette) and warm crusty bread to soak up the eggy goodness. For a complete meal, add roasted potatoes or avocado slices. The golden crust holds up well, so it’s perfect for buffet-style serving too!
