how to make Creamy Mustard Roasted Potatoes
Ingredients:
- 1.5 pounds Baby Potatoes (Small and tender)
- 2 tablespoons Extra Virgin Olive Oil
- 1 teaspoon Kosher Salt (Adjust to taste)
- 1 teaspoon Freshly Ground Pepper
- 2 tablespoons Butter (Or olive oil for dairy-free)
- 1 medium Shallot (Diced)
- 3 cloves Garlic (Minced)
- 1 cup Chicken or Vegetable Broth (Low-sodium recommended)
- 2 tablespoons Dijon Mustard
- 1 tablespoon Grainy Mustard
- 1 cup Heavy Cream (Or half-and-half)
- 2 tablespoons Cornstarch (For thickening)
- 1 cup Water (For cornstarch slurry)
- 2 tablespoons Lemon Juice
- 2 tablespoons Fresh Dill (Chopped)
Directions:
Preparation: Preheat your oven to 425°F (220°C). Wash the baby potatoes and cut them in half if they are larger. Toss them in a bowl with olive oil, salt, and pepper until well coated. Spread the potatoes evenly on a baking sheet.
Roasting the Potatoes: Roast the potatoes in the preheated oven for about 20 minutes or until they are golden brown and tender. Stir halfway through for even cooking.
Making the Sauce: In a large skillet, melt the butter (or heat olive oil) over medium heat. Add the diced shallot and minced garlic, cooking until they are soft. Then, pour in the chicken or vegetable broth. Stir in the Dijon mustard and grainy mustard.
Thickening: In a small bowl, mix the cornstarch with water to make a slurry. Add this slurry to the skillet along with the heavy cream. Stir continuously and simmer until the sauce thickens.
Final Touches: Add lemon juice and fresh dill to the sauce, mixing well. Once the potatoes are done roasting, pour the creamy mustard sauce over the potatoes in the baking sheet. Toss gently to coat.
Serving: Return the coated potatoes to the oven for an additional 5 minutes to warm everything through.
