A quick and nutritious breakfast, this Spinach and Mushroom Omelette blends protein-rich eggs with fresh vegetables for a delicious low-carb start to your day. Easy to make and packed with flavor, it’s ideal for a weekday morning or weekend brunch.
Prepare Ingredients: Begin by gathering all your ingredients and equipment to ensure a smooth cooking process. Slice 1 cup of cremini mushrooms evenly for uniform cooking. Wash and pat dry 1 cup of baby spinach to remove any excess moisture. Crack 3 large eggs into a mixing bowl and have 2 tablespoons of butter, salt, pepper, shredded cheese (if using), and 1 tablespoon of cold water ready.
Sauté Mushrooms: Place a 9-inch skillet over medium-high heat and add 1 tablespoon of butter. Allow the butter to melt completely until it becomes foamy and aromatic. Add the sliced mushrooms in a single layer and cook without overcrowding for about 5–6 minutes. Stir occasionally with a spatula to ensure even browning. The mushrooms should become golden brown and release their natural juices.
Season and Add Spinach: Once the mushrooms are golden and tender, season them with ¼ teaspoon of salt and ¼ teaspoon of black pepper. Immediately add the baby spinach to the skillet. Stir gently and cook for 1–2 minutes until the spinach wilts and reduces in size while retaining its vibrant green color. This step not only enhances flavor but also ensures the vegetables are tender yet fresh.
Remove Filling: Using a rubber spatula, transfer the sautéed mushrooms and spinach onto a clean plate. Set aside while preparing the omelette base. This ensures the vegetables retain their texture and do not overcook.
Whisk Eggs: In your mixing bowl, crack the eggs and add 1 tablespoon of cold water. Whisk vigorously until the mixture becomes smooth, pale yellow, and slightly frothy. This aerates the eggs, making your omelette fluffy and tender. A good whisking technique is key for achieving a restaurant-quality texture.
Prepare Skillet for Eggs: Wipe the skillet clean with a paper towel to remove excess oil and bits from the previous cooking step. Return the skillet to medium heat and add the remaining 1 tablespoon of butter. Allow the butter to melt completely and coat the surface evenly. The butter not only prevents sticking but also adds rich flavor to the omelette.
Cook Egg Base: Pour the whisked eggs into the skillet, letting them spread evenly. Allow them to cook undisturbed for about 1 minute until the edges begin to set. Using a rubber spatula, gently pull the edges toward the center while tilting the pan, allowing the runny egg mixture to flow to the edges. This ensures even cooking without overcooking the omelette.
Add Filling and Cheese: When the eggs are mostly set but still slightly soft on top, carefully add the sautéed mushrooms and spinach to one half of the omelette. Sprinkle ½ cup of shredded cheese over the vegetables if desired. The cheese will melt gently, creating a creamy layer that enhances the omelette’s flavor and texture.
Fold Omelette: Using the rubber spatula, carefully fold the omelette in half to cover the filling. Allow it to cook for another 30 seconds to 1 minute so the cheese melts fully and the eggs are completely set. Avoid overcooking, as this can make the omelette dry.
Serve and Enjoy: Slide the omelette gently onto a serving plate. Optionally, garnish with fresh herbs such as chives or parsley for extra flavor and visual appeal. Serve immediately while warm for the best taste and texture. This omelette pairs beautifully with fresh fruit, a light salad, or a side of avocado for a satisfying, nutrient-packed meal.
Notes
Use fresh mushrooms and spinach for the best flavor and texture. Avoid overcooking spinach to keep it vibrant and nutrient-rich.
Cold water in eggs helps create fluffier omelettes.
Adjust seasoning to taste before folding the omelette.
Cheese is optional — adding it increases richness but also adds extra calories and fat.
For a dairy-free version, use olive oil instead of butter and omit the cheese.
