Can I make this omelet dairy-free?

Absolutely. Swap the Parmesan and Cheddar for dairy-free cheese alternatives, and replace butter with coconut oil or ghee if tolerated. Use full-fat coconut cream instead of light cream.

Is it okay to use frozen zucchini?

I don’t recommend frozen zucchini, as it releases too much water and makes the omelet soggy. Fresh zucchini gives the best texture.

Can I prepare this ahead of time?

Yes, you can assemble the sautéed vegetables and egg mixture separately the night before. Combine them in the skillet right before cooking, or bake the whole omelet and reheat slices.

Instructions

Step 1

Start by preheating your oven to 350°F. In a 10-inch ovenproof skillet, sauté the zucchini and green pepper in oil over medium heat until just tender, about 3 minutes. Meanwhile, whisk together the eggs, Parmesan, cream, melted butter, salt, and pepper until well combined. Once the veggies are softened, pour the egg mixture evenly over them in the skillet. Let it cook gently on the stove for about 3 minutes, occasionally lifting the edges with a spatula to let uncooked egg flow underneath, until the bottom is set but the top is still slightly runny. Then, sprinkle the shredded Cheddar on top. Slide the skillet into the hot oven and bake for 5 to 7 minutes, or until the eggs are fully set and the cheese is bubbly and golden. I find that pulling it out when the center is just firm ensures a moist, tender omelet. Let it rest for a minute before slicing into wedges.

Chef's Tip

For an extra fluffy texture, I sometimes separate the eggs and whip the whites to soft peaks before folding them into the yolks. This gives the omelet a glorious rise and airy bite.

Storage Tips

Store leftover slices in an airtight container in the fridge for up to 3 days. Reheat gently in a microwave or nonstick pan over low heat.

Variation Tips

Try using yellow squash instead of zucchini for a sunny twist. Fold in cooked crumbled bacon or sliced olives before baking to add a salty burst. For a heartier meal, pair with creamy avocado or a fresh arugula salad.
