Egg Muffins (Easy Make-Ahead Breakfast Egg Cups)

These egg muffins are the meal prep breakfast I come back to every few weeks when the mornings get chaotic: a dozen fluffy baked egg cups loaded with turkey sausage, red pepper, spinach and cheddar, made in one bowl and one muffin tin in 30 minutes. Two muffins are 16g of protein, they reheat in a minute, and the cottage cheese whisked into the eggs keeps them tender for days instead of rubbery. They are what I grab on the mornings my freezer breakfast sandwiches run out, and they are even easier than my cottage cheese egg bites because there is no blender.

Why these egg muffins are not rubbery, watery or stuck to the pan.

• Cottage cheese in the eggs keeps them fluffy for days. Plain eggs bake into something bouncy and get worse in the fridge. A half cup of cottage cheese whisked in adds moisture and protein and makes a tender, custardy egg cup — the same reason my cottage cheese scrambled eggs stay soft.
• The vegetables are cooked first, so the bottoms are never soggy. Raw peppers and spinach leak water into the egg and leave a wet layer at the base. Four minutes in a skillet drives that moisture off first, and the muffins come out clean and firm all the way through. This is the step every meal prep breakfast egg recipe skips and regrets.
• Silicone liners or a well-greased nonstick tin, filled only three-quarters. Egg sticks to paper liners and welds itself to a bare metal tin. Silicone liners release cleanly; so does a nonstick tin brushed with oil. Fill each cup three-quarters full — they puff up in the oven and settle as they cool.

Here's what you'll need.

A dozen eggs, cottage cheese, turkey breakfast sausage, a red bell pepper, baby spinach, shredded cheddar, green onions and the basic seasonings — one bowl, one skillet, one muffin tin.

Here's how it all comes together.

STEP 1 — Cook the filling.

Heat the oven to 350°F and grease a 12-cup nonstick muffin tin well (or line it with silicone liners). Brown the turkey sausage in a skillet over medium-high heat, breaking it up, then add the diced pepper and cook 3 minutes. Stir in the spinach just until wilted and take the pan off the heat.

STEP 2 — Whisk the eggs.

Crack the eggs into a large bowl, add the cottage cheese, salt, pepper and garlic powder, and whisk until no streaks of white remain. Transfer to a measuring cup with a spout so you can pour cleanly.

STEP 3 — Divide the filling.

Spoon the sausage, pepper and spinach mixture evenly into the 12 cups, then sprinkle most of the cheddar and the green onions over the top, saving a little cheese for the finish.

STEP 4 — Pour and top.

Pour the egg mixture over the filling, stopping three-quarters of the way up each cup. Give each one a gentle stir with a fork so the filling is suspended rather than sitting at the bottom, and scatter the reserved cheddar on top.

STEP 5 — Bake and cool.

Bake 18 to 22 minutes until the centers are set and the tops are just starting to turn golden. Let them cool in the tin 5 minutes — they will deflate slightly, which is normal — then run a knife around the edges and lift them out onto a rack.

Things I learned while testing this recipe.

• Grease the tin like you mean it, or use silicone. My first batch in a lightly sprayed metal tin left half of every muffin behind. Brush oil into every cup and up the sides, or buy a set of silicone liners once and never think about it again. Paper liners are the worst option — egg glues itself to paper.
• Cook the vegetables first, every time. I tested a "dump it all in raw" version to see if the extra step mattered. It did: watery bottoms and pale, steamed peppers. Four minutes in a skillet is worth it.
• Do not overbake. Pull them when the centers are just set and no longer jiggly — about 20 minutes in most ovens. Another 5 minutes turns them spongy, and they tighten more as they cool and again when you reheat them.
• Season more than you think. Eggs and vegetables need salt. A full teaspoon of kosher salt for a dozen eggs is right, plus the sausage and cheese. Under-seasoned egg muffins are why people stop making egg muffins.

Why these egg muffins are my favorite high protein meal prep breakfast.

• 16g protein for two muffins, about 190 calories. Eggs, cottage cheese, turkey sausage and cheddar stack up fast. Two muffins with a piece of fruit is a real breakfast; three with avocado is a post-workout one. Check your own numbers in the protein calculator.
• They keep 5 days in the fridge and 3 months in the freezer. Cool completely, then store in an airtight container with a paper towel on the bottom to catch any moisture. For the freezer, wrap each muffin individually or flash-freeze on a tray before bagging.
• Infinitely customizable with whatever is in the fridge. Swap the sausage for bacon or ham, the pepper for mushrooms or broccoli, the cheddar for feta or pepper jack. Keep the total add-ins to about 2 cups cooked and the egg-to-filling ratio stays right.

Here's what I'd serve with this.

• Air fryer sweet potato fries — a breakfast-for-dinner plate with two of these
• Greek yogurt bagels — split, toasted, egg muffin inside — a 2-minute sandwich
• Pumpkin overnight oats — something sweet to pair with the savory cups
• High protein chia pudding — prep both on Sunday for a full week of breakfasts
• Cowboy caviar — spooned over a warm egg muffin like salsa

Just in case you have leftovers.

Storing: Cool completely, then refrigerate in an airtight container lined with a paper towel for up to 5 days. Freeze individually wrapped for up to 3 months.

Reheating: From the fridge: microwave 2 muffins for 45 to 60 seconds, or warm in the air fryer at 300°F for 4 minutes. From frozen: microwave 90 seconds to 2 minutes, flipping halfway, or thaw overnight in the fridge first.
