Ingredients You’ll Need

• 10 large eggs – the base of the muffins, creating structure and protein.
• 1 Tbsp olive oil – for sautéing the vegetables and managing moisture.
• ½ yellow onion, chopped
• 1 red bell pepper, chopped
• 2 cloves garlic, minced
• ½ zucchini, shredded and well drained
• 1 cup arugula, roughly chopped (or substitute baby spinach)
• 2 Tbsp milk – a splash of milk helps create a softer texture; any milk works, including plant-based varieties.
• 1/3 cup freshly grated Parmesan cheese – adds savory depth and helps bind the muffins.
• ½ tsp salt and ¼ tsp black pepper – to taste.

How to Make Veggie Egg Muffins

1. Preheat and prepare the pan. Preheat oven to 350°F (175°C). Lightly grease a 12-cup muffin tin with nonstick spray or a little olive oil.
2. Sauté the vegetables. Heat the olive oil in a skillet over medium heat. Cook the chopped onion and red bell pepper for 3–4 minutes until softened. Add the minced garlic and cook 30 seconds more. Remove from heat and let cool slightly.
3. Drain the zucchini. Shred the zucchini and squeeze out as much liquid as possible using a clean kitchen towel or paper towels. Removing moisture prevents soggy muffins.
4. Combine the egg mixture. In a large bowl, whisk together the eggs, milk, Parmesan, salt, and pepper until slightly frothy. Stir in the sautéed vegetables, shredded zucchini, and chopped arugula until evenly distributed.
5. Fill the muffin cups and bake. Divide the mixture evenly among the 12 muffin cups, filling each about three-quarters full to allow room for puffing. Bake 20–25 minutes, or until centers are set and tops are lightly golden.
6. Cool and serve. Let the muffins cool for about 5 minutes before removing from the pan. Serve warm, or cool completely and store for meal prep.

Recipe Tips for the Best Results

• Squeeze the zucchini well – this is the most important step to prevent watery muffins.
• Sauté vegetables first – cooking onions, peppers, and garlic concentrates flavor and reduces excess moisture.
• Use freshly grated Parmesan for better melt and richer flavor compared with pre-shredded cheese.
• Fill cups to about ¾ full so the muffins can puff without spilling over.
• Allow a short cooling time before removing from the pan so the muffins firm up and come out cleanly.
• Silicone pans or liners make removal and cleanup easier, though a small offset spatula or butter knife also helps loosen edges.

Variations and Substitutions

• Add protein: fold in cooked turkey sausage, diced ham, or crumbled bacon for extra heartiness.
• Swap the greens: baby spinach, kale, or chard work well in place of arugula.
• Mix different vegetables: mushrooms, broccoli, cherry tomatoes, asparagus tips, or green onions are all tasty options.
• Try other cheeses: sharp cheddar, mozzarella, feta, or goat cheese will change the character of the muffins.
• Dairy-free: use a plant-based milk and omit the cheese or add a dairy-free alternative.
• Add herbs and spices: Italian seasoning, red pepper flakes, fresh basil, or parsley add extra flavor.
• Mini muffins: divide the batter into a 24-cup mini muffin tin and bake 12–15 minutes for smaller portions.

Storage, Freezing, and Reheating

• To store: cool completely, then keep in an airtight container in the refrigerator for up to 5 days.
• To freeze: place cooled muffins in a freezer-safe container or bag for up to 3 months.
• To reheat: microwave an individual muffin about 20–30 seconds from the fridge, or 45–60 seconds from frozen. Reheat in an air fryer at 300°F for 3–4 minutes for a crisp exterior and warm center.
