How to Make It

Getting started on your Creamy Mustard Roasted Potatoes is a simple yet engaging process that unravels with each step, filling your kitchen with enticing smells that whet your appetite. Here’s how to make it happen:

Prep the Base

First things first, let’s bring that oven to life! Preheat it to 400°F (200°C) while you prepare the main star—our lovely baby potatoes. Rinse them under cool water, their smooth skins glistening in the light. Place these vibrant orbs onto a baking sheet. Drizzle with a generous amount of extra virgin olive oil, allowing it to glisten against their surfaces. Season them lovingly with kosher salt and a sprinkle of fresh pepper. Using your hands, toss them gently to ensure every potato is coated in that golden oil, before spreading them evenly out. As they roast in the oven for 35 to 40 minutes, the kitchen transforms, filled with the comforting scent of earthy potatoes browning beautifully as they become tender yet slightly crispy.

Build the Flavor

While that’s happening, let’s dive into creating your luxurious sauce. In a skillet over medium heat, add a tablespoon of butter alongside a splash of olive oil. As it warms, wait for that delicious sizzle as the butter dissolves. Toss in the finely diced shallots, their signature sweetness releasing into the air as they soften gently for about three to four minutes. The comforting aroma intensifies as you then add minced garlic, sautéing for just another minute until fragrant and golden.

Carefully introduce your broth to this floral and warm mixture, bringing it to a gentle simmer. This is where the magic truly begins! Whisk in the Dijon and grainy mustards, followed by a sprinkle of kosher salt and pepper, letting these flavors mingle and reduce by a third, creating a rich and savory base that will wrap around your potatoes like a cozy blanket.

Create the Creamy Sauce

Now, it’s time to bring in the heavy cream for that luxurious touch. Pour the cream into the reduced broth and bring it back to a simmer, watching as the mixture thickens and transforms. To achieve that dreamy consistency, combine cornstarch and water in a small cup to create a slurry. As you whisk this in with the simmering sauce, feel the delight in knowing you’re just moments away from pure deliciousness. In barely a minute, the sauce will thicken to perfection before you finish with a squeeze of fresh lemon juice and a quick taste to check the seasoning.

Finish & Serve

As the final touch, your potatoes are likely nearing the end of their roasting journey, exuding a delicious aroma that promises comfort. Retrieve them from the oven, their surfaces beautifully caramelized and alluring. In a serving bowl, arrange a layer of luscious potatoes, then generously spoon over your creamy mustard sauce. Sprinkle with freshly chopped dill—its vibrant green a feast for the eyes and palate alike. Continue this delightful layering until the bowl is full, and you have a stunning centerpiece for your table.

Now gather around, as everyone will be drawn to this comforting creation, ready to savor your Creamy Mustard Roasted Potatoes—a dish that speaks to the heart.

Creative Twists

While this recipe is already a delightful celebration of flavors, here are a few creative twists to keep it interesting through the seasons:

Seasonal Upgrades: In the fall, add roasted pumpkin or butternut squash cubes for a cozy autumnal touch. In summer, consider tossing in some fresh peas for a bright, sweet contrast.
Herb Infusions: For a fragrant upgrade, try incorporating rosemary or thyme along with the fresh dill for an aromatic twist that pairs beautifully with the creamy sauce.
Zesty Variations: Swap in different mustards for an unexpected flavor—try a spicy brown mustard for a kick, or a whole grain mustard for an added texture.
Veggie Additions: Create a complete meal by introducing blanched green beans or sautéed spinach into the mix, adding color and nutrition.
Protein Pairing: Elevate your dish by serving the potatoes alongside grilled chicken or roasted salmon, with the creamy sauce drizzled over the protein.
