Shopping List

• Large eggs (10–12, depending on muffin size and add-ins)
• Fresh spinach (4 cups loosely packed) or frozen chopped spinach (1 cup, thawed and well-drained)
• Shredded cheese (1 to 1 1/2 cups) – cheddar, mozzarella, Monterey Jack, or a blend
• Milk or half-and-half (1/3 to 1/2 cup)
• Olive oil or butter (1 tablespoon, if sautéing fresh spinach)
• Green onions or chives (optional, 2–3 tablespoons, finely sliced)
• Garlic powder (1/2 teaspoon) or 1 small clove garlic, minced
• Salt (about 1/2 to 3/4 teaspoon)
• Black pepper (1/4 teaspoon)
• Optional add-ins: cooked bacon or sausage, diced bell pepper, mushrooms, sun-dried tomatoes, feta, hot sauce
• Nonstick spray or muffin liners

Step-by-Step Instructions

1. Preheat and prep the pan: Heat your oven to 350°F (175°C).

   Lightly grease a 12-cup muffin pan with nonstick spray or line with parchment liners. Greasing the top of the pan helps prevent sticking if the egg mixture spills slightly.

2. Wilt or prep the spinach: If using fresh spinach, warm a skillet with a little olive oil over medium heat. Add spinach and cook 1–2 minutes until wilted, then let it cool and squeeze out excess moisture.

   If using frozen spinach, thaw completely and squeeze dry in a clean towel. Excess water will make the muffins soggy.

3. Beat the eggs: In a large bowl, whisk eggs until fully blended and slightly frothy. Whisk in milk or half-and-half to add a bit of creaminess and prevent a rubbery texture.
4. Season: Add salt, black pepper, and garlic powder.

   If using fresh garlic, add it here. Stir in sliced green onions or chives, if using.

5. Add cheese and spinach: Fold in shredded cheese and the well-drained spinach. If you’re adding cooked bacon, sausage, or veggies, fold those in now as well.
6. Fill the muffin cups: Divide the mixture evenly among the 12 cups, filling each about 3/4 full.

   Give the pan a gentle tap on the counter to settle the mixture.

7. Bake: Place on the center rack and bake 16–22 minutes, or until the muffins are puffed, set in the center, and lightly golden around the edges. A toothpick should come out mostly clean.
8. Cool briefly: Let the muffins rest in the pan for 5 minutes. Run a thin knife around the edges to loosen, then transfer to a wire rack to finish cooling.

   This helps prevent condensation and sogginess.

9. Serve: Enjoy warm with hot sauce, salsa, sliced avocado, or a dollop of Greek yogurt. They’re also great in a breakfast sandwich.

How to Store

• Refrigerator: Keep muffins in an airtight container for up to 4 days. Let them cool fully before sealing to prevent moisture buildup.
• Freezer: Wrap each muffin individually in plastic wrap or parchment, then place in a freezer-safe bag.

  Freeze up to 2 months. Label with the date for easy tracking.

• Reheat: Microwave refrigerated muffins for 20–30 seconds. From frozen, microwave 45–60 seconds, or thaw overnight in the fridge and heat for 20–30 seconds.

  For crisper edges, warm in a 325°F (165°C) oven for 8–10 minutes.

Health Benefits

• Protein for staying power: Eggs and cheese offer high-quality protein that helps keep you full and steady through the morning.
• Iron and folate: Spinach provides iron and folate, both important for energy and overall wellness. Pairing spinach with vitamin C (like a side of fruit) may support iron absorption.
• Calcium and B vitamins: Cheese adds calcium for bones and B12 for energy metabolism.
• Vegetable intake made easy: Getting greens at breakfast sets a healthy tone for the day and boosts fiber.
• Balanced macros: With protein, fat, and optional fiber-rich veggie add-ins, these muffins can help prevent mid-morning crashes.

What Not to Do

• Don’t skip draining the spinach: Excess water will make the muffins weepy and dense. Squeeze it well.
• Don’t overfill the cups: Overfilling leads to overflow and sticking.

  Aim for about 3/4 full.

• Don’t overbake: Dry, rubbery egg muffins are usually baked too long. Pull them when the centers are just set.
• Don’t add raw, watery veggies without pre-cooking: Mushrooms, zucchini, and tomatoes should be sautéed and drained first.
• Don’t skip greasing: Even with liners, a light spray helps the muffins release cleanly.

Recipe Variations

• Greek-style: Use feta, chopped spinach, red onion, and a few sun-dried tomatoes. Add a sprinkle of dried oregano.
• Meaty and hearty: Stir in cooked crumbled sausage or bacon with sharp cheddar and a pinch of smoked paprika.
• Veggie lovers: Add sautéed mushrooms, bell peppers, and onions with mozzarella or provolone.
• Spicy kick: Mix in diced jalapeños, pepper jack cheese, and a splash of hot sauce.
• Dairy-light: Use less cheese and swap milk for an unsweetened dairy-free option like almond milk.

  Add nutritional yeast for a cheesy vibe.

• Herb forward: Fold in chopped parsley, dill, or basil for fresh flavor without extra calories.

FAQ

Can I use egg whites instead of whole eggs?

Yes. Use about 2 cups of liquid egg whites for a 12-muffin batch. Add a little extra cheese or a tablespoon of olive oil to improve texture and flavor since whites are leaner.

Why did my muffins deflate after baking?

Egg muffins will puff in the oven and settle as they cool, which is normal.

If they collapse a lot, they may have too much liquid or were underbaked. Make sure spinach and veggies are well-drained and bake until the centers are just set.

How do I keep them from sticking?

Grease the muffin pan generously, including the top surface, or use parchment liners. Let the muffins rest for 5 minutes, then run a thin knife around the edges before lifting them out.

What cheese works best?

Cheddar, mozzarella, Monterey Jack, Swiss, or a blend all melt nicely.

For a sharper flavor, use aged cheddar or a little Parmesan. Feta adds tang but doesn’t melt as smoothly, so consider mixing it with a melty cheese.

Can I make these the night before?

You can whisk the egg mixture and prep the fillings the night before. Store separately in the fridge and assemble just before baking for the best rise and texture.

Baked muffins also reheat well the next day.

How can I make them more filling?

Add protein like cooked turkey sausage or bacon, and include fiber-rich veggies. Pair with whole-grain toast, berries, or sliced avocado for a balanced meal.

Are these good for kids?

Absolutely. Keep the flavors simple, chop veggies small, and choose a mild cheese.

You can also bake mini muffins for smaller hands; reduce bake time by a few minutes.
