There’s something about the aroma of roasted vegetables that feels like comfort. The sizzle from the oven, the caramelized edges, the burst of flavor when you take the first bite—it’s the kind of side dish that steals the spotlight. That’s exactly what happened the first time I made lemon dijon roasted carrots. They weren’t planned as the star of the meal, but one taste—and they absolutely were.
These carrots are a mix of earthy sweetness and bright citrus, with just enough sharpness from the mustard to wake up your taste buds. Roasted until tender with golden edges, they’re finished with a drizzle of lemony sauce and crumbled feta if you’re feeling fancy. Whether you’re serving them with grilled chicken or a holiday roast, they’re the kind of dish that makes people say, “Wait, what’s in this?”
A Carrot Dish That Changed the Game
The Night I Fell in Love with Roasted Carrots
It was an early spring dinner party—one of those casual get-togethers with a mix of neighbors, potluck-style. I had planned to make a simple tray of roasted carrots. Nothing flashy, just a quick side to go along with the lemon herb chicken someone else was bringing.
But I had a jar of Dijon mustard sitting on the counter and half a lemon in the fridge, and something about the combo felt right. I whisked together a little lemon juice, mustard, and honey, tossed it with the carrots, and threw in some garlic and dill for good measure.
What came out of the oven looked ordinary—but the smell was anything but. Tangy, sweet, herby. I brushed them with the leftover marinade during the last few minutes of roasting and topped them with feta at the end.
Guests were raving. Someone asked if I had used orange zest. Another thought it was a secret glaze. I just smiled and passed the plate around again.
Why Lemon and Dijon Are the Perfect Match
Carrots are naturally sweet—but without balance, that sweetness can fall flat. That’s where lemon and Dijon come in. Lemon juice brightens and cuts through the richness. Dijon brings just enough sharpness to contrast the honey, enhancing the carrot’s flavor without overpowering it.
Together, they transform a humble vegetable into something bold and memorable.
Lemon Dijon Roasted Carrots
Ingredients
- 1 lb. carrots washed & peeled
- 1 Tbsp avocado oil
- 2 Tbsp lemon juice divided
- 1 Tbsp dijon mustard
- 1 Tbsp honey
- 2 garlic cloves minced
- 1 Tbsp fresh dill chopped (or 1 tsp dried dill)
- ¼ tsp salt
- Black pepper to taste
- ¼ cup feta cheese crumbled (optional)
Instructions
- Preheat your oven. Turn your oven on to 425 degrees and line a baking sheet with parchment paper.
- Prepare your carrots. Slice both ends off your carrots. Then cut your carrots on the bias (diagonally) into thirds or roughly into 1½ inch pieces and place them in a large bowl. (You may need to slice the larger pieces in half again lengthwise if they’re too big.)
- Toss the carrots. Whisk your oil + 1 tablespoon of lemon juice + a ½ tablespoon of dijon mustard + a ½ tablespoon honey together and pour it over your carrots. Add your garlic, dill, salt and cracked black pepper to taste and toss until the carrots are fully coated.
- Using a slotted spoon, remove the carrots from the bowl and spread them out onto your prepared pan. (Reserve the liquid in your bowl to brush over the carrots later.)
- Roast. Place the pan in the oven and roast for 20-25 minutes or until tender. During the last 5-10 minutes brush your reserved liquid over the carrots.
- Make your sauce. Once done, mix your remaining 1 tablespoon of lemon juice + ½ tablespoon of dijon mustard + ½ tablespoon of honey together and drizzle the sauce over your carrots.
- Serve. Toss the carrots and serve immediately with crumbled feta sprinkled over the top (if desired).
Choosing and Preparing the Best Carrots
What Kind of Carrots Work Best for Roasting
The beauty of lemon dijon roasted carrots is that they don’t need to be fancy—but picking the right type of carrot does make a difference. Standard whole carrots are perfect for this recipe. Look for ones that are firm, vibrant in color, and free of blemishes or soft spots. These hold up well to high heat and caramelize beautifully.
Bagged baby carrots are convenient, but they tend to release more moisture and don’t roast as evenly. If you’re in a rush, they’ll still work, but expect a slightly softer texture and less browning.
You can also use rainbow carrots for a colorful twist. Their natural sweetness varies slightly by color, which adds visual appeal and subtle complexity.
Whatever you choose, peeling the carrots is key. It removes any bitterness from the skin and helps the marinade soak in better. Uniform size is just as important—cutting them to the same thickness ensures they roast evenly. If some pieces are much larger than others, the smaller ones will burn before the big ones finish cooking.
How to Cut and Season for Flavor and Even Cooking
The way you slice your carrots affects both flavor and presentation. Cutting on the bias—diagonally—creates longer, angled pieces that roast quickly and look elegant on the plate. Each slice gets more surface area for browning, and that’s where all the flavor lives.
Once cut, the carrots get tossed in a bold marinade: avocado oil for richness, lemon juice for brightness, Dijon mustard for tang, and honey for balance. Add minced garlic and fresh dill to layer in even more flavor. A little salt and black pepper pull it all together.
Here’s the trick: after tossing, use a slotted spoon to transfer the carrots to the baking sheet. That way, the extra liquid stays behind and doesn’t steam the carrots during roasting. Save that flavorful marinade—because later, it’s going right back on top.
This simple prep step ensures your lemon dijon roasted carrots roast evenly, brown beautifully, and soak up all that bold, zesty flavor.
Roasting to Perfection
Should You Boil Carrots Before Roasting?
It’s a common question: Do I need to boil carrots before roasting? The short answer? No—and please don’t.
Roasting raw carrots at a high temperature is what gives you those sweet, caramelized edges and tender insides. Boiling first not only adds an unnecessary step but also pulls flavor and nutrients out of the carrots and into the water. You end up with a softer texture, but less of the rich, roasted taste that makes this dish shine.
The key to great lemon dijon roasted carrots is to roast them straight on a hot pan. This keeps the outside beautifully browned while the inside stays tender with just the right bite.
Tips for Oven Roasting That Delivers Every Time
Start by preheating your oven to 425°F and lining your baking sheet with parchment paper. This high heat ensures a fast roast that caramelizes without drying things out. You want the carrots to sizzle when they hit the pan.
After tossing your carrots in the lemon-dijon-honey mixture and seasoning, use a slotted spoon to lift them out of the bowl. This removes excess liquid, which can cause steaming instead of roasting.
Spread the carrots out in a single layer—overcrowding is a mistake that leads to soggy results. If you’re doubling the recipe, use two pans.
Roast for 20 to 25 minutes, flipping once halfway through. In the last 5–10 minutes, brush the reserved marinade over the carrots. This step adds a glossy finish and boosts flavor right at the end.
When they’re fork-tender and the edges are golden-brown, they’re ready. The aroma will tell you before the timer does—it’s lemony, sweet, and deeply savory all at once.
These tips don’t just improve texture—they build flavor from the inside out, turning ordinary carrots into a side dish that’s hard to forget.
Finishing Touches & Serving Ideas
The Simple Sauce That Takes It Over the Top
One of the best parts of these lemon dijon roasted carrots happens after they leave the oven.
While they roast, you’ve already reserved a bit of your lemon-honey-dijon mixture. But once the carrots are out and lightly browned, you’ll mix up a fresh drizzle: 1 tablespoon lemon juice, ½ tablespoon dijon mustard, and ½ tablespoon honey.
This final touch isn’t cooked—it’s bright, tangy, and fresh. When drizzled over the warm carrots, it soaks in just enough to boost flavor without overpowering the roasted notes. The result? A side that’s both savory and zippy, with a clean citrus finish that wakes up the entire plate.
This sauce is also what separates a good roasted vegetable from a great one. It adds moisture, complexity, and makes the dish feel finished, not just cooked.
Garnishes and Pairing Ideas
If you want to take these carrots even further, crumbled feta is the move. Its creamy, salty bite contrasts beautifully with the tangy glaze and earthy sweetness of the carrots. Just a sprinkle over the top before serving is all you need.
You can also finish with extra chopped dill, parsley, or even a little lemon zest for color and brightness.
As for what to serve these with? They’re incredibly versatile. Pair them with grilled chicken, roasted salmon, lamb chops, or a hearty grain salad. They’re elegant enough for a holiday table, but quick enough for a Tuesday night dinner.
Don’t be surprised if they get more attention than the main dish. These carrots shine on their own—and the best part is, they’re just as good at room temp the next day.
Frequently Asked Questions
Is it necessary to boil carrots before roasting?
No. Boiling carrots before roasting isn’t necessary and can actually water down their flavor. Roasting them raw allows the natural sugars to caramelize, creating better texture and deeper taste.

What is the best seasoning for roasted carrots?
It depends on your flavor profile, but a mix of lemon juice, dijon mustard, garlic, dill, and honey makes for a bold, balanced seasoning. Salt and pepper are essential, and fresh herbs or spices like cumin, coriander, or thyme also pair well.
How long should I roast carrots in the oven?
At 425°F, roast carrots for 20 to 25 minutes, depending on their thickness. Flip halfway through for even browning. You’ll know they’re ready when they’re fork-tender with caramelized edges.
