Ingredients Overview

Each ingredient plays an important role in creating the light, fluffy texture and savory Mediterranean-inspired flavor profile of these egg muffins.

Eggs

• Whole Eggs: Provide protein, structure, and healthy fats. Use large eggs for standard measurements.
• Optional Egg Whites: For a lighter version, replace some whole eggs with whites to reduce cholesterol and fat.

Spinach

• Fresh Baby Spinach: Adds fiber, vitamins A & C, and a vibrant green color. Sautéing beforehand removes moisture and concentrates flavor.
• Frozen Spinach: Works as a substitute—just thaw and squeeze out all excess water.

Feta Cheese

• Crumbled Feta: Brings a creamy, tangy flavor that pairs perfectly with eggs and greens. Choose a block and crumble it yourself for best texture.

Milk or Cream

• Whole Milk or Half-and-Half: Helps create a fluffy, custardy texture. You can substitute with plant-based options like unsweetened almond or oat milk.

Aromatics & Additions

• Garlic & Onion Powder: Add savory depth without the need for sautéing fresh aromatics.
• Salt & Pepper: Essential for flavor balance.
• Optional Add-ins:
  • Diced bell peppers or tomatoes
  • Cooked mushrooms or zucchini
  • Fresh herbs like dill, parsley, or chives
  • A pinch of chili flakes for heat

Substitutions:

• Dairy-Free: Omit feta or use a plant-based cheese.
• Low-FODMAP: Use green onions instead of garlic or onion powder.
• Keto-Friendly: Skip the milk or use heavy cream for fewer carbs.

Step-by-Step Instructions

1. Preheat and Prep

• Preheat oven to 350°F (175°C).
• Grease a 12-cup muffin tin with nonstick spray or line with silicone muffin liners for easy removal.

2. Sauté the Spinach

• In a skillet, heat 1 tsp olive oil over medium heat.
• Add 2 cups fresh spinach and sauté until wilted (1–2 minutes).
• Let cool slightly, then chop or press out excess moisture if needed.

3. Whisk the Egg Base

• In a large mixing bowl, whisk together:
  • 6 large eggs
  • 1/4 cup milk or half-and-half
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1/4 tsp garlic powder
  • 1/4 tsp onion powder

4. Fold in Fillings

• Stir in:
  • Cooked spinach
  • 1/3 cup crumbled feta
  • Any optional mix-ins (chopped veggies or herbs)

5. Fill and Bake

• Divide the egg mixture evenly among the 12 muffin cups (about 3/4 full).
• Bake for 18–22 minutes, or until the tops are puffed and a toothpick comes out clean.
• Let cool in the tin for 5 minutes before removing.

Pro Tips:

• Don’t overfill — the muffins will puff during baking.
• For even cooking, use the center rack and rotate the pan halfway through if your oven has hot spots.
• These muffins collapse slightly as they cool — totally normal!

Tips, Variations & Substitutions

• Make it Meaty: Add diced cooked bacon, turkey sausage, or ham for extra protein.
• Switch the Cheese: Try goat cheese, shredded cheddar, or Swiss for a different flavor profile.
• Go Greek: Add sun-dried tomatoes and Kalamata olives along with the feta for a Mediterranean twist.
• Make It Vegan: Use JUST Egg or a tofu-based egg substitute and omit the cheese or use vegan feta.

Storage & Reheating:

• Refrigerate for up to 5 days in an airtight container.
• Reheat in the microwave for 20–30 seconds or in a 300°F oven for 5–6 minutes.
• Freeze for up to 2 months; thaw overnight in the fridge or microwave straight from frozen.
