Equipment
- Medium saucepan
- Whisk
- Chef's knife
- Cutting board
- Measuring spoons
- Measuring cups
- Wooden spoon or silicone spatula
- Box grater (for cheese)
Ingredients
- 2 tablespoons unsalted butter
- 1 small shallot, finely minced
- 2 cloves garlic, minced
- 2 tablespoons all-purpose flour
- 1 cup chicken broth, preferably low-sodium
- 1 cup heavy cream
- 1 tablespoon Dijon mustard
- 1 teaspoon Worcestershire sauce
- 1 cup shredded Gruyère or Swiss cheese
- ¼ cup grated Parmesan cheese
- Salt and freshly ground black pepper, to taste
- Fresh parsley, chopped, for garnish
Instructions
- In a medium saucepan over medium heat, melt the butter. Once foaming, add the minced shallot and cook for 2-3 minutes until softened and translucent.
- Add the minced garlic and cook for 30 seconds until fragrant, stirring constantly. Do not let the garlic brown.
- Sprinkle the flour over the shallot and garlic. Whisk constantly for about 1 minute to create a pale golden roux.
- Slowly pour in the chicken broth while whisking vigorously to prevent lumps. Once smooth, add the heavy cream, Dijon mustard, and Worcestershire sauce. Whisk until fully combined.
- Bring the sauce to a gentle simmer (small bubbles around the edges). Reduce heat to low and cook for 3-4 minutes, stirring occasionally, until thickened enough to coat the back of a spoon.
- Remove the saucepan from the heat. Add the shredded Gruyère and grated Parmesan cheese. Stir gently until the cheese is completely melted and the sauce is smooth and glossy.
- Taste and season with salt and pepper as needed (remember the cheese and ham are salty, so go easy on the salt).
- Pour the warm sauce over freshly cooked chicken tenders. Garnish with fresh parsley and serve immediately.
Notes
For a flavor boost, brown the butter before adding the shallot until it turns golden and smells nutty. Add a pinch of fresh nutmeg or a few sprigs of fresh thyme while the sauce simmers. To make gluten-free, substitute the flour with a 1:1 gluten-free flour blend or a cornstarch slurry (1 tbsp cornstarch mixed with 2 tbsp cold water, added at the end). Store leftover sauce in an airtight container in the refrigerator for up to 3 days; reheat gently over low heat, adding a splash of milk or broth if needed to restore consistency.
