About This Recipe

These air fryer mini frittatas are the sort of breakfast that feels both indulgent and deliberately efficient: a custardy egg base flecked with salty ham, tender wilted spinach, bright green onion, and tangy feta. The air fryer gives you a gently bronzed edge and a set center in under 15 minutes without the worry of a soggy bottom that can plague oven-baked minis. Whisking the eggs with a splash of milk creates a light lift, while reserving a little feta on top delivers a briny, golden hit as the cheese warms and crisps.

They’re perfect for anyone who likes breakfast that travels—kids’ lunchboxes, commuters, or anyone packing a post-workout protein boost. The portion control is built in, and the simple ingredient list makes swaps easy: use turkey or a smoked fish, add herbs for brightness, or fold in roasted peppers for sweetness. Because these hold their texture when chilled and reheat beautifully in an air fryer or microwave, they’re as useful for meal prep as they are for last-minute company, making them a weeknight lifesaver with a restaurant-worthy start.

Ingredients for Air Fryer Mini Frittatas with Ham, Spinach, and Feta

  • 1 tsp Olive oil (or cooking spray) for greasing
  • 8 large Large eggs
  • 1/4 cup Whole milk
  • 3/4 cup Cooked ham, diced
  • 1 cup Fresh spinach, chopped
  • 1/2 cup Feta cheese, crumbled
  • 2 stalks Green onions, thinly sliced
  • 1/2 tsp Kosher salt
  • 1/4 tsp Freshly ground black pepper

How to Make Air Fryer Mini Frittatas with Ham, Spinach, and Feta

  1. Step 1: Preheat and grease molds

    Preheat the air fryer to 325°F (163°C) for about 3 minutes. Lightly grease a silicone 12-cup mini-muffin tray or six 6-oz ramekins with olive oil or cooking spray to prevent sticking.

    For this step

    • 1 tspOlive oil (or cooking spray) for greasing
  2. Step 2: Prep the fillings

    Dice the cooked ham, chop the spinach, thinly slice the green onions, and crumble the feta. Divide a small amount of feta to reserve for topping each frittata if you like a golden, salty finish.

    For this step

    • 3/4 cupCooked ham, diced
    • 1 cupFresh spinach, chopped
    • 1/2 cupFeta cheese, crumbled
    • 2 stalksGreen onions, thinly sliced
    Prep the fillings
  3. Step 3: Whisk the egg base

    In a medium bowl, whisk together the eggs and milk until combined and slightly frothy, then season with the kosher salt and black pepper. Whisking aerates the eggs for a lighter texture and ensures even seasoning.

    For this step

    • 8 largeLarge eggs
    • 1/4 cupWhole milk
    • 1/2 tspKosher salt
    • 1/4 tspFreshly ground black pepper
    Whisk the egg base
  4. Step 4: Assemble the mini frittatas

    Fold the diced ham, chopped spinach, sliced green onions, and most of the crumbled feta into the egg mixture. Pour the mixture into the greased molds, filling each about three-quarters full, and top each with a pinch of reserved feta.

  5. Step 5: Air fry, cool, and serve

    Air fry at 325°F (163°C) for 10–12 minutes, or until the centers are set and a toothpick comes out clean. Let the mini frittatas cool in the tray for 3–5 minutes before removing; serve warm or cool completely and refrigerate for make-ahead breakfasts.

Air Fryer Mini Frittatas with Ham, Spinach, and Feta Tips

Squeeze Wilted Spinach

If you sauté frozen or excess-wet spinach, squeeze it dry before adding to the eggs to avoid watery frittatas and ensure a firm set.

Room-Temperature Eggs

Bring eggs to room temperature for a smoother, more even rise; cold eggs can reduce the lift you get from whisking.

Don't Overfill Cups

Fill molds about three-quarters full to prevent spilling and to leave room for the frittatas to puff slightly as they cook.

Test for Doneness

Insert a toothpick into the center—if it comes out mostly clean and the surface is springy, they’re done; carryover heat will finish any tiny bit of custard.

Use a Light Oil Spray

A quick spritz of oil prevents sticking without adding excess fat that can pool and make the bottoms greasy.

Air Fryer Mini Frittatas with Ham, Spinach, and Feta Variations and Substitutions

Vegetarian Spinach-Feta

Omit the ham and fold in diced roasted red peppers and a pinch of smoked paprika for a sweet-smoky counterpoint to the feta.

Mediterranean Twist

Replace ham with chopped sun-dried tomatoes and kalamata olives, and add a teaspoon of dried oregano for a briny, herb-forward profile.

Dairy-Free Option

Use unsweetened almond or oat milk and skip the feta or substitute with a firm dairy-free cheese; drain greens thoroughly to keep texture right.

Smoked Salmon Version

Swap ham for small pieces of smoked salmon and add dill and a little lemon zest to the egg mix for a brunch-worthy upgrade.

How to Store and Make Air Fryer Mini Frittatas with Ham, Spinach, and Feta Ahead

Store cooled frittatas in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze individually wrapped portions for up to 2 months; thaw overnight in the fridge before reheating. Reheat from chilled in the air fryer at 350°F (175°C) for 3–4 minutes to restore a slightly crisp edge, or microwave for 25–45 seconds depending on your appliance.

What to Serve With Air Fryer Mini Frittatas with Ham, Spinach, and Feta

Serve warm with a simple green salad dressed in lemon vinaigrette and a slice of crusty whole-grain toast for a balanced plate. For grab-and-go mornings, tuck two minis into a paper bag with sliced avocado or a small cup of mixed berries, and pair with black coffee or a bright citrus smoothie.

Air Fryer Mini Frittatas with Ham, Spinach, and Feta FAQs

Can I use frozen spinach in these?

Yes—thaw it fully and squeeze out as much moisture as possible before folding into the eggs to avoid excess water that will prevent proper setting.

Do I need a silicone tray or ramekins?

Silicone is convenient for easy removal, but metal ramekins work well too; just grease them thoroughly and check a minute or two earlier since metal transfers heat more aggressively.

How do I avoid rubbery eggs?

Whisk eggs just until combined, use a splash of milk for tenderness, and avoid overcooking—remove when the centers are set but still springy to the touch.

Can I make these ahead for the week?

Absolutely—make a batch and refrigerate for up to 4 days or freeze for longer; reheat in the air fryer to refresh the texture before serving.

What if I don't have an air fryer?

Bake mini frittatas in a 350°F (175°C) oven for 12–16 minutes, checking for doneness with a toothpick and rotating the tray halfway through for even browning.
