Ingredients

For the omelette

4 large eggs
2 tablespoons heavy cream or unsweetened almond milk for a lighter option
1 tablespoon unsalted butter or olive oil, for cooking the mushrooms
1 tablespoon unsalted butter for cooking the eggs
1 cup sliced mushrooms such as cremini or white button
1/4 teaspoon garlic powder optional, for extra flavor
1/4 teaspoon sea salt plus more to taste
1/8 teaspoon black pepper freshly ground, plus more to taste

Optional toppings and add-ins

1/2 cup shredded cheese such as cheddar, mozzarella, or a blend
2 tablespoons chopped fresh herbs such as chives, parsley, or thyme
1/2 medium avocado sliced, for serving

Instructions

Crack the eggs into a mixing bowl, add the heavy cream, salt, and black pepper, and whisk until the mixture is smooth, slightly frothy, and well combined.
Place a nonstick skillet over medium heat and add the first tablespoon of butter or olive oil, allowing it to melt and coat the bottom of the pan.
Add the sliced mushrooms to the hot skillet and cook, stirring occasionally, until they release their moisture and become golden brown around the edges, about five to seven minutes.
Season the mushrooms with garlic powder and a small pinch of additional salt and pepper, then cook for another minute until fragrant and transfer them to a small plate.
Reduce the heat to medium low, add the second tablespoon of butter to the same skillet, and let it melt and gently coat the pan without browning too much.
Pour the egg mixture into the skillet and let it sit undisturbed for a short moment until the edges just begin to set, then gently push the cooked edges toward the center while tilting the pan so uncooked egg flows to the edges.
When the top surface of the eggs is still slightly soft but mostly set, evenly scatter the cooked mushrooms over one half of the omelette and sprinkle with shredded cheese if using.
Cover the skillet briefly with a lid for one to two minutes until the cheese melts and the eggs finish setting to a soft, fluffy texture without becoming dry or rubbery.
Use a spatula to carefully fold the bare half of the omelette over the mushroom side, slide the omelette onto a plate, and garnish with fresh herbs and sliced avocado if desired.
Serve the omelette hot and enjoy immediately, or allow it to cool slightly before refrigerating in an airtight container for up to two days for a quick reheatable keto meal.

Notes

For the best texture, keep the heat at medium low so the eggs cook gently and stay tender rather than turning dry. Make sure to brown the mushrooms well before adding them to the eggs so they do not release excess moisture into the omelette. You can customize this keto omelette by adding cooked bacon, diced ham, or a small handful of chopped spinach while still keeping carbs low. Reheat leftovers in a covered nonstick skillet over low heat or in short microwave bursts to avoid overcooking the eggs.
