If you love the indulgence of classic French cuisine but need to keep your meals low-carb, this Keto Croque Monsieur Omelette is the perfect high-fat, low-carb alternative. Inspired by the traditional café favorite, this recipe transforms the classic ham-and-cheese sandwich into a savory, creamy, crustless omelette with only 4g net carbs per serving.
Ingredients
- 2 eggs
- 25 g grated cheese (Gruyère, Swiss, or cheddar work well)
- 25 g ham (1 large slice, preferably nitrate-free)
- 40 ml heavy cream
- 40 ml mascarpone cheese
- 30 g butter
- Salt and pepper to taste
- Fresh basil leaves for garnish (optional)
Instructions
- Crack the eggs into a bowl. Add salt and pepper to taste.
- Add the heavy cream, mascarpone, and grated cheese to the eggs. Whisk until the mixture is smooth and well combined.
- Heat a frying pan over medium heat and melt the butter. Be careful not to brown the butter.
- Reduce heat to low. Pour in half of the egg mixture and quickly place the slice of ham over it.
- Pour the remaining egg mixture over the ham, then immediately cover the pan with a lid.
- Let cook for 2–3 minutes over low heat, just until the top starts to firm slightly.
- Slide the omelette onto the lid, flip it gently, and return it to the pan. Cook another 1–2 minutes covered. It’s okay if it remains slightly soft inside.
- Remove from heat and garnish with fresh basil if desired. Serve hot!

Why This Keto Croque Monsieur Is Perfect for Low-Carb Lifestyles
Traditional Croque Monsieur sandwiches are loaded with carbs from bread and flour-based sauces. This keto adaptation skips the bread entirely and replaces the béchamel with rich mascarpone and cream, maintaining the luxurious flavor without the carb load.
Mascarpone and heavy cream are rich in healthy fats that help keep you full and support ketosis. According to the USDA, mascarpone provides 44g of fat per 100g and virtually zero carbs, making it a keto-friendly dairy option.
Eggs are an excellent source of protein and micronutrients like choline and B12. Paired with ham and cheese, they create a balanced macro profile ideal for ketogenic diets.
Serving Suggestions
- Pair with a light arugula salad tossed in olive oil and lemon juice for added greens.
- Serve with a side of sautéed spinach or roasted asparagus for a hearty brunch.
- Top with a fried egg if you’re feeling extra indulgent (turns it into a Keto Croque Madame!).
Storage Tips
This dish is best served fresh, but leftovers can be refrigerated in an airtight container for up to 24 hours. Reheat gently on the stovetop to maintain its creamy texture.
Final Thoughts
The Keto Croque Monsieur Omelette is a clever, quick, and delicious way to enjoy French flavors without compromising your carb limits. With its rich, creamy texture and savory ham and cheese, this dish feels indulgent yet keeps you within your macros.
