Ingredients for apple flour egg

Six eggs, sharp cheddar, and the secret apple flour blend create this restaurant-worthy frittata.

The apple flour blend is the game-changer here. Bob's Red Mill or King Arthur carry excellent pre-ground apple flour, but if you're ambitious, blend dried apple slices in a food processor for a fresher taste. For the cheese, Cabot or Tillamook cheddars deliver that perfect sharpness—avoid pre-shredded, which contains anti-caking agents that prevent proper melting. The heavy cream adds richness without overpowering the delicate apple notes, while the olive oil in the crust ensures a crispy, golden finish that contrasts beautifully with the fluffy interior.

No apple flour? Substitute 1/4 cup almond flour plus 1/4 cup all-purpose flour for a nutty alternative, though the texture will differ slightly. Running short on chives? Fresh dill or basil work in a pinch, though chives provide that signature oniony brightness. The red bell pepper and onion can be swapped for any sautéed vegetable—zucchini, mushrooms, or spinach all pair well. For extra depth, toast the apple flour blend lightly in a dry pan before mixing—it intensifies the apple flavor without burning. If you're making this ahead, use full-fat dairy for best reheating results.

Store any leftovers in an airtight container for up to 3 days in the refrigerator, though this frittata reheats beautifully—just 30 seconds in the microwave or until warmed through in a skillet. For meal prep, slice into wedges and freeze between parchment paper for up to 2 months. The crust stays crispy when reheated gently, while the egg center remains tender. To serve, pair with a simple arugula salad dressed with lemon vinaigrette for a complete brunch plate that feels both elegant and effortless.

Step-by-step instructions for apple flour egg recipe

Master this savory frittata technique for a golden crust and fluffy interior every time.

Heat the 1 tablespoon extra-virgin olive oil in a 10-inch oven-safe skillet over medium heat. Add the 0.5 cup finely diced yellow onion and 0.5 cup diced red bell pepper, cooking for 5-6 minutes until the onions become translucent and the peppers soften slightly.

Add the 2 cloves minced garlic and cook for 30 seconds until fragrant—don't let it brown. Season immediately with ½ teaspoon ground black pepper and ½ teaspoon Diamond Crystal kosher salt. The vegetables should be tender but still hold their shape when pressed with a spoon.

In a medium bowl, whisk together the 0.5 cup apple flour blend and 0.25 cup all-purpose flour with 1 teaspoon Diamond Crystal kosher salt. Cut in the 2 tablespoons cold cubed unsalted butter using a fork or pastry cutter until the mixture resembles coarse crumbs with pea-sized butter pieces.

Add the 0.25 cup heavy cream and mix until just combined—don't overwork. The crust should be crumbly but hold together when pressed. Spread this mixture evenly over the sautéed vegetables in the skillet, pressing down gently with the back of a spoon to create an even layer.

In a separate large bowl, whisk the 6 whole large eggs until the yolks and whites are fully combined. Add the 1.5 cups shredded extra-sharp white cheddar cheese and whisk until evenly distributed. Pour this egg mixture evenly over the crust layer in the skillet.

Transfer the skillet to a preheated 375°F oven and bake for 20-25 minutes until the edges are golden brown and the center is just set. You'll see the top puff slightly and develop a crisp crust around the edges—this is your visual cue it's ready.

Remove the frittata from the oven and let it rest for 5 minutes before slicing. This resting period allows the custard to set properly. Use a sharp knife to cut into 4 equal wedges for serving.

Garnish each portion with the 0.25 cup finely chopped fresh chives and 0.25 cup finely chopped fresh parsley. The herbs should be sprinkled evenly over each wedge to add both color and freshness. Serve immediately while the crust remains crisp and the interior stays moist.

Essential equipment for this recipe

Oven-Safe Skillet

An oven-safe skillet is your best friend for this recipe—I recommend a 10-inch cast iron skillet like the Lodge Pre-Seasoned Cast Iron Skillet. Cast iron distributes heat evenly and retains it beautifully, ensuring your crust gets perfectly crispy while the eggs cook through evenly.

If you don’t have cast iron, a stainless steel skillet with an oven-safe handle (like All-Clad Stainless) works well too. Just avoid non-stick—it won’t handle the high heat needed for that golden crust. 🔥

Mixing Tools

For the crust mixture, use a fork or pastry cutter to cut in the cold butter—this creates the perfect crumbly texture without overworking the flour. I love my OXO Good Grips Pastry Cutter for this step because it’s easy to handle and gives consistent results.

For whisking the eggs, a balloon whisk (like the Cuisinart Stainless Steel Balloon Whisk) is ideal—it incorporates air beautifully, giving you that light, fluffy texture. A regular fork works in a pinch, but the balloon whisk makes all the difference. ✨

Measuring Cups

Precision matters with the apple flour blend—use a dry measuring cup (like OXO Good Grips Dry Measuring Cups) for accurate measurements. Apple flour is lighter than all-purpose flour, so packing it down can lead to a dense crust.

For the heavy cream and olive oil, a liquid measuring cup (like Pyrex Glass Liquid Measuring Cup) ensures you get the right amount without spills. I also recommend a small kitchen scale (like OXO Good Grips Digital Scale) for the butter—it’s more accurate than volume measurements. 💡

Cheese Grater

A fine-hole cheese grater (like the Microplane Cheese Grater) is essential for shredding the cheddar evenly. Pre-shredded cheese contains anti-caking agents that prevent proper melting, so fresh shredding is a game-changer. If you don’t have a dedicated cheese grater, a box grater with small holes works too.

Just be patient—this step makes a huge difference in the final texture and flavor of your frittata. 🧀

Knife Set

A sharp chef’s knife (like Wüsthof Classic 8-Inch) and a paring knife are must-haves for dicing the onion, bell pepper, and garlic. Sharp knives make prep faster and safer, and they help you achieve the even, small dice needed for this recipe.

I also recommend a cutting board with a juice groove (like John Boos End Grain Cutting Board) to catch any liquid from the vegetables. A dull knife is dangerous and makes chopping harder—keep yours honed with a Wüsthof Honing Steel. 🌶️

Optional: Food Processor

If you’re making your own apple flour blend from dried apple slices, a food processor (like the Ninja BN601 Foodi) is a game-changer. Pulse the dried apples until they reach a fine, flour-like consistency—about 30-45 seconds on high.

This method gives you fresher flavor and more control over the texture. If you don’t have one, a high-powered blender (like Vitamix 5200) works too, but a food processor is more efficient for small batches. 🍎
