- Roasted Potatoes:
- 3 lbs baby potatoes (mixed yellow/red skins)
- 3 tbsp extra virgin olive oil
- 1½ tsp kosher salt
- ½ tsp black pepper
- Mustard Cream Sauce:
- 1 tbsp unsalted butter
- 1 tbsp olive oil
- 1 shallot, finely diced
- 2 garlic cloves, minced
- 1 cup chicken or vegetable broth
- 2 tbsp Dijon mustard
- 1 tbsp grainy mustard
- 1 cup heavy cream
- 1 tbsp cornstarch + 1 tbsp water (slurry)
- 1 tbsp fresh lemon juice
- ¼ cup chopped fresh dill
- Salt and pepper to taste
- 1. Preheat oven to 400°F. Halve larger baby potatoes. Toss with olive oil, salt, and pepper on parchment-lined baking sheet. Roast 35-40 minutes until golden and tender, flipping halfway.
- 2. While potatoes roast, make sauce: Heat butter and olive oil in skillet over medium. Sauté shallot 3-4 minutes until soft. Add garlic; cook 1 minute.
- 3. Add broth, both mustards, ½ tsp salt, ¼ tsp pepper. Simmer 5 minutes until reduced by third. Stir in cream; simmer. Whisk in cornstarch slurry; boil 1 minute until thickened. Add lemon juice and dill; season to taste.
- 4. Layer potatoes and sauce in serving bowl, sprinkling dill between layers. Serve warm.
Notes
- Baby potatoes hold shape best; larger ones need parboiling first.
- Use quality mustards Dijon for smoothness, grainy for texture.
- Make-ahead: Roast potatoes day before; reheat sauce gently.
- Vegetarian/vegan: Use vegetable broth and coconut cream substitute.
- Leftovers keep 3 days refrigerated; reheat with splash of cream.
