Roasted Rainbow Carrots

If you want a side dish that looks like you actually tried (without, you know… actually trying), these Glazed Rainbow Carrots are your new best friend!

They’re bright, they’re glossy and they bring that roasted, caramelized goodness that just works with everything.

The glaze is sweet, tangy, a little zesty, and it cooks down into a gorgeous coating that clings to every glazed carrot, creating sticky, golden edges and soft centres that still have a bit of bite.

They make any table look instantly better - festive spread, Sunday roast, weeknight “I found carrots in the fridge” situation… all of it.

🌱 Ingredients & Notes

Here is everything you need for this recipe:

• Rainbow carrots - Go for a mix of colors; they roast the same, but look far more fun. Slice larger ones lengthwise so they cook evenly. You can also use purple carrots, white carrots, baby carrots or regular orange carrots. Use fresh carrots, not frozen for the best results.
• Agave syrup - Brings sweetness that caramelizes beautifully. Alternatively, you can also use maple syrup or brown sugar.
• Extra virgin olive oil - Adds richness and helps the glaze coat the carrots.
• Dijon mustard - Gives the glaze a bright, tangy kick.
• Apple cider vinegar - Balances everything with a bit of acidity. You can swap for balsamic vinegar for a tangier flavor.
• Dried thyme - Light savoury note. Swap for fresh if you prefer.
• Fresh herbs - Such as fresh parsley, for a pop of fresh color.

🧑‍🍳 Instructions (Step-by-Step)

Step 1 - Preheat:

Heat the oven to 200°C (180°C fan) and line a baking sheet or a large baking dish with parchment.

Step 2 - Prep the carrots

Wash and trim them. Halve thicker carrots lengthwise so they roast evenly. Spread them on the baking sheet in a single layer.

Step 3 - Make the glaze

Add agave syrup, olive oil, Dijon, apple cider vinegar, thyme, salt, and pepper to a small saucepan. Warm gently until smooth and slightly thickened.

Step 4 - Coat

Pour the glaze over the carrots and toss (or brush) so everything is coated.

Step 5 - Roast

Bake for 20-25 minutes, turning halfway. You're looking for tender carrots with caramelized edges.

Step 6 - Serve

Transfer to a dish and sprinkle with parsley.

🍽️ Serving

Serve these warm as a colorful side dish for:

• Roast mains (vegan or not)
• Festive spreads
• Grain bowls or hearty salads
• Sheet pan meals or weeknight stews

They also make your table instantly look more intentional - even if you threw dinner together last minute.

❄️ Storage

Keep leftovers in an airtight container for up to 3 days.

How to reheat

To reheat simply use:

• A skillet over low heat (best texture)
• Or the oven at a low temp

Avoid the microwave - it softens them too much and makes them sad and soggy.

Equipment

• 1 Pastry brush or tongs to coat the carrots
• 1 Knife and cutting board
• 1 mixing bowl optional but handy for tossing

Ingredients

  

• 1.1 lb rainbow carrots (500g) trimmed and washed
• 2 tablespoons agave syrup
• 2 tablespoons extra virgin olive oil
• 2 tablespoons Dijon mustard
• 1 tablespoons apple cider vinegar
• 1 pinch of dried thyme
• Salt and pepper to taste
• Fresh parsley chopped, for garnish

Instructions

 

• Preheat the oven to 200°C (180°C fan) and line a baking tray.

• In a small saucepan, warm the agave, oil, Dijon, vinegar, thyme, salt, and pepper until smooth.

Notes

• Serving: These glazed rainbow carrots are best served warm as a beautiful side dish for roast mains, festive spreads, or simple weeknight dinners. They also work well in grain bowls or alongside hearty salads.
• Storage: Store leftovers in an airtight container in the fridge for up to 3 days.
• Reheating: Reheat gently in a skillet over low heat or in the oven until warmed through. Avoid the microwave if possible, as it softens the carrots and dulls the glaze.
• Even roasting: If some carrots are much thicker than others, slice them lengthwise so everything cooks at the same speed.
• Glaze texture: For a slightly looser glaze, add an extra teaspoon of olive oil. For a brighter finish, add a small squeeze of lemon just before serving.
• Herb swap: Fresh thyme works well here - use roughly double the amount compared to dried.
• Sweetener swap: Maple syrup can be used instead of agave for a slightly deeper, caramel-style sweetness.
