About the Ingredients
2 lbs (900g) baby potatoes, halved
Baby potatoes are creamy and cook quickly. Yukon Gold or red potatoes work great; if using larger potatoes, cut into 1-inch chunks.
3 tablespoons olive oil
Extra virgin olive oil adds rich flavor. You can substitute with avocado oil for a higher smoke point.
2 tablespoons fresh rosemary, chopped
Fresh rosemary is aromatic and pairs beautifully with roast beef. Dried rosemary works in a pinch – use 2 teaspoons.
4 cloves garlic, minced
Fresh garlic is key. For a milder taste, roast the garlic cloves whole; for convenience, use 1 teaspoon garlic powder.
1 lb (450g) carrots, peeled and sliced diagonally
Look for firm, bright orange carrots. Rainbow carrots add a pop of color; baby carrots can be used without slicing.
2 tablespoons honey
Honey adds natural sweetness and helps caramelization. Maple syrup or agave nectar are excellent substitutes.
1 tablespoon fresh thyme leaves
Thyme's earthy notes complement the honey. Dried thyme – 1 teaspoon – is a good substitute.
2 tablespoons butter, melted
Unsalted butter gives you control over seasoning. For a dairy-free option, use vegan butter or olive oil.
1/2 cup sour cream
Full-fat sour cream is best for a creamy sauce. Greek yogurt is a lighter alternative.
2 tablespoons prepared horseradish
Prepared horseradish adds a tangy kick. Adjust the amount to your heat preference; cream-style horseradish is milder.
1 tablespoon Dijon mustard
Dijon adds a subtle sharpness. Whole grain mustard is a great substitute for extra texture.
Salt and freshly ground black pepper, to taste
Seasoning is crucial – use kosher salt for even distribution and freshly cracked pepper for aroma.
Tips & Tricks
- To get extra crispy potatoes, parboil them for 5 minutes before roasting, then shake them in the pot to rough up the edges.
- Don't overcrowd the baking sheet – give the potatoes and carrots space to brown properly; use two pans if needed.
- For the horseradish sauce, let it sit in the fridge for at least 30 minutes before serving to allow the flavors to meld.
Pro Tips
Step-by-Step Instructions
1. Preheat & Prep
Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or foil for easy cleanup.
2. Season the Potatoes
In a large bowl, toss the halved baby potatoes with 2 tablespoons of olive oil, 1 tablespoon of rosemary, half of the minced garlic, salt, and pepper. Ensure each potato is well coated.
3. Roast the Potatoes
Spread the potatoes in a single layer on the prepared baking sheet, cut side down. Roast for 25-30 minutes, flipping halfway, until golden brown and crispy on the edges, and a fork inserts easily.
4. Glaze the Carrots
While the potatoes roast, in a separate bowl, toss the carrot slices with the remaining 1 tablespoon olive oil, honey, thyme, butter, salt, and pepper.
5. Roast the Carrots
After the potatoes have been roasting for 15 minutes, add the carrots to the same sheet (or a second sheet) in a single layer. Roast for 15-20 minutes, stirring once, until tender and caramelized at the edges.
6. Make the Sauce
In a small bowl, mix the sour cream, prepared horseradish, Dijon mustard, and a pinch of salt and pepper. Stir until smooth. Cover and refrigerate until serving.
7. Finish & Serve
Once the potatoes and carrots are done, transfer them to a serving platter. Sprinkle with the remaining fresh rosemary and thyme. Serve hot with the horseradish sauce on the side.
Delicious Variations
- Add a sprinkle of smoked paprika to the potatoes for a smoky depth of flavor.
- Swap honey for maple syrup and add a pinch of cayenne to the carrots for a sweet-spicy twist.
- Stir in some caramelized onions to the horseradish sauce for extra sweetness and texture.
How to Store Roast Beef Dinner Side Dishes
Refrigerator
Store leftovers in an airtight container in the fridge for up to 3 days.
Freezer
Potatoes and carrots can be frozen in a single layer on a baking sheet, then transferred to a freezer bag for up to 2 months. The sauce is best made fresh.
Reheating
Reheat in a 375°F (190°C) oven for 10 minutes until warmed through and crispy. For the sauce, stir in a little milk if needed.
Frequently Asked Questions
Q: Can I make these sides ahead of time?
Yes, you can roast the potatoes and carrots up to 2 hours ahead and reheat them in the oven before serving. The horseradish sauce can be made a day in advance.
Q: What can I substitute for horseradish?
You can use Dijon mustard mixed with a bit of lemon juice and a pinch of cayenne for a similar kick, or simply use extra Dijon mustard for a milder sauce.
Q: How do I get the potatoes extra crispy?
Parboil the potatoes for 5 minutes, then drain and shake them in the pot to rough up the edges. This creates a starchy coating that crisps up beautifully in the oven.
Q: Can I use frozen vegetables?
Frozen carrots and potatoes can be used, but they will release more moisture, so they may not get as crispy. Thaw and pat them dry before roasting.
