Ingredients for This Creamy Mushroom Omelette Recipe
This ingredient list for this onion and mushroom omelette will be extremely small, which is perfect for when you’re super hungry in the morning and you’re itching to get a healthy breakfast on the table!
How to Make Creamy Mushroom Omelette
Heat a pan on medium heat and add butter to the pan.
When the pan is hot, add sliced mushrooms and onions.
Cook for 3-5 minutes, until the mushrooms are brown and the onions are golden brown.
Transfer to a small bowl and set aside.
Now prepare the omelette. Add 1 egg and 2 egg whites to a small bowl.
Whisk well to combine and season with salt and pepper.
Add the eggs to the pan.
Add the sautéed onions and mushrooms over the omelette.
Put a lid on the pan and cook for 3-4 minutes.
Remove the lid from the pan when the eggs are no longer translucent.
Fold the omelette in half, serve hot, and enjoy!
What Mushrooms to Use in This Mushroom Onion Omelette?▼
I like to keep things very simple when it comes to mushrooms. My favorite trio is white button mushrooms, cremini mushrooms or portobello mushrooms. I recommend all three and they are always easy to find and light on that wallet.
I prefer picking my mushrooms individually rather than getting a package of mushrooms so I can ensure quality.
Is This Creamy Mushroom Omelette Healthy?▼
Eggs make for a staple breakfast option for good reason. They are packed with nutrients, are a good source of protein, healthy omega-3 fats and keep you feeling full. Given a healthy blood cholesterol level, whole eggs are an amazing, low-calorie breakfast food (Source: WebMD).
While mushrooms are packed with antioxidants, especially Selenium, which is known to help protect the body against free radicals which can cause conditions like heart disease and cancer. In addition, mushrooms are packed with fiber, vitamins and minerals, and might I add - so delicious (Source: Healthline).
