Some people are a little scared to make omelettes because they seem fragile and difficult to make, but trust me when I say the tips below will ensure that your steak omelette, or any other omelette for that matter, turns out perfectly.

Why you'll love this steak omelette recipe

• Protein-packed: Between the eggs and the steak, this dish is full of protein, making it a breakfast that will stick to your bones.
• Fantastic use of leftovers: We make these steak omelettes whenever we have leftover steak. You only need a handful of vegetables, too, so it's perfect for the last of a pepper, an onion, or whatever other vegetables you have on hand.
• Quick and easy: Omelettes might seem a little complex to some people, but they're actually really easy and take only 15 minutes to make 2 omelettes.
• Customizable: The basics of making an omelette are in the instructions, but what you fill it with is entirely up to you. Make use of whatever you have when it comes to the protein, the vegetables, and the cheese.

Ingredients needed for a Steak Omelette

• Butter: For cooking the vegetables and the omelettes.
• Vegetables: onion, bell peppers, and white mushrooms.
• Eggs
• Cheddar cheese: Thinly sliced.
• Steak: Thinly sliced- This is a great recipe for leftover steak. We made our steak omelette with leftovers from our Cajun Beef Tenderloin. Yum! Another great way to use leftover steak is this recipe for Greek Style Steak Crostini.

How to Make a Steak Omelette

1. Melt 1 tablespoon of butter in a skillet over medium high heat.
2. Add onions, peppers, and mushrooms and cook until onions are translucent, about 8 minutes. Salt to taste and set aside.
3. Lower the heat to medium low and add another tablespoon of butter.
4. Whisk eggs in a small bowl. Pour half of the eggs in the skillet.
5. Let eggs cook undisturbed for 2 minutes. Gently lift cooked edges and tilt the skillet to let raw eggs run underneath. Continue until egg on top is no longer liquid.
6. Flip omelette carefully and immediately layer half of the omelette with cheddar cheese. Top cheese with half of the vegetables and half of the sliced steak.
7. Fold the empty half of the omelette over the vegetables and steak and carefully remove from pan.
8. Add remaining butter to the pan. When melted, repeat steps with remaining eggs, cheese, vegetables, and steak.

Expert Tips

• Be sure that the pan you use is non-stick!
• The trick is to get all the omelette stuffing hot before adding it to the omelette without overcooking the steak. I like to do this by getting the steak sliced first and allowing it to come to room temperature. Then, I cook the vegetables and, while still hot, I just toss the steak with the vegetables.
• As your omelette cooks, gently lift the edges with a spatula and tilt the pan to let raw egg from the top run underneath. Once there isn't enough raw egg on top to "run" anywhere, it is time to flip!
• The easiest way to get an omelette out of the pan is not by lifting the omelette, but lifting the pan. Tilt the pan over your plate and let the omelette gently slide out of the pan onto the plate.

Substitutions and Variations

• Replace the steak with any protein you have on hand! Leftover fajita or taco meat would be perfect with these vegetable combo!
• Likewise, you can also replace the vegetables with whatever you have on hand.
• Add fresh herbs to step up your omelette game.
• Switch out the cheddar cheese for another more creative cheese. I think provolone would be amazing with this omelette, and pepper jack would give it a nice little kick.

Storage Tips

Refrigerator

Omelettes are best served immediately after eating as the texture of the eggs will change upon refrigeration and reheating. That said, an omelette will last in the fridge in an airtight container for up to 3 days.

Freezer

Wrapped in an airtight container with the air removed, a steak omelette can be frozen for up to 2 months.

Reheating

Let your steak omelette thaw completely before reheating. Reheat it gently in the microwave in 20 second increments until heated through.

What to serve with a Steak Omelette

This is a complete protein-packed meal on its own! If you'd like a side dish I recommend fresh fruit.

If you are making a whole breakfast spread with your steak omelettes, these would be perfect served with Asiago Cheese and Black Pepper Biscuits and Pimento Cheese Grits.
