Start your day with a warm, savory Mushroom and cheese omelette that’s creamy, satisfying, and perfectly suited for a keto or low-carb lifestyle. This classic breakfast combines earthy mushrooms, melty cheese, and fluffy eggs for a quick meal that’s high in healthy fats and protein while keeping carbs very low.
Why this Mushroom and cheese omelette works for keto
- High fat and moderate protein from eggs, butter, cream, and cheese help keep you satiated.
- Very low total carbohydrates and minimal fiber yield an extremely low net-carb count — ideal for ketogenic and low-carb meal plans.
- Fast to make (10 minutes) and easy to customize.
Ingredients (serves 1)
- 3 large eggs
- 1/2 cup (about 35 g) sliced white or cremini mushrooms
- 1/4 cup (about 28 g) shredded cheddar cheese (or your favorite hard cheese)
- 1 tablespoon unsalted butter
- 1 tablespoon heavy cream (optional, for extra fluffiness)
- Salt and freshly ground black pepper, to taste
- Fresh chives or parsley, finely chopped (optional, for garnish)
Step-by-step recipe
- Prep: Clean and slice mushrooms. Grate cheese if not pre-shredded. Crack eggs into a bowl, add heavy cream, a pinch of salt and pepper, and whisk until uniform and slightly frothy.
- Sauté mushrooms: Heat a nonstick skillet over medium heat, add butter and let it melt. Add sliced mushrooms and a pinch of salt; sauté until they release moisture and turn golden, about 3–4 minutes. Push mushrooms to the side or remove briefly.
- Cook eggs: Lower heat to medium-low. Pour the egg mixture into the skillet and let it set gently around the edges. Tilt skillet and lift edges with a spatula so uncooked egg flows underneath.
- Add cheese: When the eggs are nearly set but still slightly soft on top, sprinkle shredded cheddar evenly over half the omelette. Add mushrooms back on top of the cheese if you’d moved them.
- Fold and serve: Fold the omelette in half over the filling, cook another 30–60 seconds to melt cheese. Slide onto a plate, garnish with fresh chives or parsley, and enjoy.

Keto and low-carb tips
- To reduce carbs further, use smaller portions of mushrooms or substitute with lower-carb options like baby spinach (very low carbs).
- Increase fat for a more ketogenic profile by adding an extra tablespoon of butter or a tablespoon of olive oil.
- For fewer carbs and lactose, choose aged hard cheeses (they generally have fewer carbs) or omit the cream.
- Serve with low-carb sides: avocado slices, a small mixed greens salad with olive oil, or bacon/sausage.
Variations and add-ins
- Herb and garlic: Sauté mushrooms with a small crushed garlic clove and fresh thyme.
- Spinach & feta: Replace cheddar with feta and add a handful of wilted spinach.
- Bacon & mushroom: Add crispy cooked bacon pieces for extra flavor and fat.
- Dairy-free option: Use a dairy-free butter substitute and omit or replace cheese with a keto-friendly dairy-free cheese.
Storage and reheating
- Best eaten fresh. If you must store: wrap tightly and refrigerate up to 24 hours. Reheat gently in a low oven (250–300°F / 120–150°C) or in a nonstick skillet over low heat to avoid rubbery eggs.
