How to Make Garlic Sauce Baby Potatoes
Preheat the Oven
Position a rack in the center of the oven and preheat to 425°F (220°C). Line a large baking sheet with parchment paper if desired. Preheating the oven ensures that the potatoes roast evenly and develop a nice golden color.
Season the Potatoes
Place the baby potatoes in a large bowl. Toss with the olive oil, salt, black pepper, and garlic powder until evenly coated. This step is crucial as it helps the seasonings adhere to the potatoes and enhances their flavor during roasting.
Roast the Potatoes
Arrange the potatoes cut-side down in a single layer. Roast for 35 to 40 minutes, turning once halfway through, until the potatoes are golden brown and easily pierced with a fork. If they are not yet tender, continue roasting in 5-minute intervals. The goal is to achieve a crispy exterior while keeping the inside fluffy.
Cook the Garlic
About 10 minutes before the potatoes finish roasting, melt the butter in a large skillet over medium-low heat. Add the minced garlic and cook for about 1 minute, stirring constantly, until fragrant. Do not allow the garlic to brown, as this can lead to a bitter taste in the sauce.
Build the Sauce
Sprinkle the flour over the garlic butter and whisk continuously for 1 minute. Slowly whisk in the milk and heavy cream until smooth. This step creates a roux that will help thicken the sauce, ensuring a creamy texture.
Thicken the Sauce
Bring the mixture to a gentle simmer over medium-low heat, whisking frequently for 3 to 5 minutes until it lightly coats the back of a spoon. This simmering process allows the flavors to meld and the sauce to thicken properly.
Finish the Sauce
Reduce the heat to low. Stir in the Parmesan cheese, Dijon mustard, dried parsley, salt, and black pepper until smooth and creamy. If the sauce becomes too thick, whisk in 1 to 2 tablespoons of milk. The cheese adds richness and depth to the sauce, making it more flavorful.
Coat the Potatoes
Add the hot roasted potatoes to the skillet and gently fold until every potato is coated with the garlic sauce. Avoid stirring too vigorously to prevent breaking the potatoes. This ensures that each potato is evenly covered in the creamy sauce without losing its shape.
Serve
Transfer the potatoes to a serving dish. Sprinkle with fresh parsley and additional Parmesan cheese, if using. Serve immediately while hot. Serving right away keeps the potatoes warm and the sauce creamy.
Tips for Success
- Roast the potatoes cut-side down for the best caramelization.
- Avoid overcrowding the baking sheet so the potatoes roast instead of steam.
- Cook the garlic over moderate heat to prevent bitterness.
- Grate the Parmesan finely for the smoothest sauce.
- Add a splash of warm milk if the sauce thickens too much before serving.
Storage, Freezing, and Make-Ahead Instructions
Refrigerate leftover Garlic Sauce Baby Potatoes in an airtight container for up to 4 days. Reheat gently in a covered skillet over medium-low heat with a splash of milk until the potatoes are heated through and the sauce is smooth. Alternatively, microwave individual portions in short intervals, stirring between each, until they reach 165°F (74°C). Freezing is not recommended because cream-based sauces can separate and the potatoes may become grainy after thawing. For make-ahead preparation, roast the potatoes and prepare the garlic sauce separately up to 1 day ahead. Refrigerate both, then gently reheat the sauce, thinning it with milk if needed, before tossing with the warmed potatoes.
FAQ
Can I boil the potatoes instead of roasting them?
Yes. Boil the potatoes until fork-tender, drain well, and allow them to dry briefly before adding them to the sauce. Roasting, however, provides a richer flavor and crisp edges.
Why did my garlic sauce become too thick?
Cream sauces continue thickening as they cool. Whisk in warm milk a tablespoon at a time until the desired consistency returns.
Can I make this recipe ahead of time?
Yes. Roast the potatoes and prepare the sauce separately. Reheat both just before serving and combine while hot.
Can I add herbs?
Yes. Fresh thyme, chives, rosemary, or dill pair well with the garlic sauce. Add delicate herbs near the end of cooking for the brightest flavor.
What can I serve with Garlic Sauce Baby Potatoes?
They pair well with roasted chicken, grilled steak, pork chops, baked salmon, shrimp, meatloaf, or roasted vegetables.
