Portobello Cordon Bleu with Dijon Cream Sauce: the most flavorful remix of a comfort food classic. Made with melty Swiss cheese, juicy Black Forest ham, tender portobello mushrooms, and a tangy dijon cream sauce, then baked to perfection and ready in 30 minutes.
Ingredients in Portobello Cordon Bleu
- Mushrooms: I like to use portobello mushrooms in this recipe because they are the perfect size and they add a flavor that perfectly compliments the Swiss cheese, ham, and tangy dijon cream sauce. (More mushroom recipes here.)
- Ham: any kind of ham will work, I prefer using thinly sliced Black Forest ham. You could also use bacon, pancetta, or prosciutto. All of these would make delicious options.
- Swiss cheese: while this isn't your traditional cordon bleu recipe, it has the two main elements: ham, and Swiss cheese. This Portobello Cordon Bleu with Dijon Cream Sauce is also excellent with smoked mozzarella or sharp white cheddar. Check out this Chicken Cordon Bleu recipe.
- Pork Rinds: pork rinds a great option for a zero carb breading. If you are not a fan of pork rinds, you can use a mix of grated parmesan cheese and blanched almond flour. Alternatively, you can use my Nut Free Keto Breading Recipe.
Step by Step Instructions
How to make keto Cordon Bleu
STEP 1: First, preheat oven to 400°F. Line a baking sheet with parchment paper or a silicone baking mat. Remove the stems from mushroom caps and slice a thin layer off of the top of the mushroom cap to allow it to sit flat.
2: Next, remove the gills and brush the mushrooms with olive oil and sprinkle with a little salt and pepper. Bake for 12 minutes.
3: Chop the mushroom stem and cap pieces.
4: In a large sauté pan, over medium heat, sauté chopped mushrooms in butter, and garlic for 5 minutes.
5: Add heavy cream, chicken broth and parsley. Allow to come to a boil over medium heat and then reduce heat to low. Add ¼ cup of the Parmesan cheese and the Dijon to sauce. Simmer on low, stirring occasionally and allow the sauce to thicken.
6: Fill the mushroom caps with sauce.
7: Layer with ham, cheese, ham, cheese. Top with another dollop of sauce and thin layer of crushed pork rinds and the remaining parmesan cheese on top of the sauce.
8: Lastly, bake for 7 minutes more at 400°F. Then broil on high for 2 to 3 minutes or until the top is golden brown. Garnish with chives before serving.
Recipe Tips and Variations
- Serving suggestions: I like to serve these with Buttery Cauliflower Rice Pilaf, or Paprika Roasted Radishes
- Storage: store in an airtight container in the fridge for up to 3 days.
- Reheating: I recommend reheating this Portobello Cordon Bleu with Dijon Cream Sauce in the oven or air fryer at 350°F for about 5 minutes.
- Add more protein: Add a bit of shredded rotisserie chicken or pulled pork to up the protein in this recipe. The dijon cream sauce is great to reuse and add a creamy element to any protein.
- Add more veggies: add in some roasted cauliflower, broccoli, or caramelized onions.
- Change up the cheese: smoked mozzarella, sharp white cheddar, or even Gruyere cheese would be a great option.
- Switch up the flavor: add sauerkraut and swap the ham for corned beef serve with keto Russian dressing for a more Reuben inspired flavor combination. You can also try these Reuben Stuffed Mushrooms. You could also swap the dijon cream sauce with a creamy dill sauce, like in this Pork Tenderloin with Creamy Dill Sauce.
