Key Ingredients for the Roasted Potatoes with Vegetables Salad

potatoes, kale, cauliflower, rosemary, garlic, olive oil, mustard, vinegar, salt and pepper laid out for roasting potatoes.

Baby potatoes: They require little prep and are more tender on the inside.

Fresh rosemary: This fresh herb is the perfect choice for adding a rich flavor to roasted vegetables.
Olive oil: For roasting the vegetables.

How to make Roasted Potatoes with Vegetables tossed with a Dijon Vinaigrette

Step 1: Prepare the equipment

Preheat the oven to 400F then line a large baking sheet with parchment paper.

Step 2: Prepare the potatoes and cauliflower

Clean the potatoes then cut them into small pieces and place them into a large bowl with the cauliflower florets, rosemary, olive oil, and salt. Toss gently to combine.

Step 3: Bake the vegetables

Arrange the veggies in a single layer on the parchment-lined sheet pan. Roast stirring once halfway through, in the oven for 40-45 minutes or until potatoes are tender and cauliflower is golden brown and caramelized on the edges.

Step 4: Prepare kale

While vegetables are roasting, wash the kale with cold water and dry it, then remove the thick stems. Using your hands, massage the chopped kale with a little bit of olive oil until it becomes tender, wilted, dark green and the volume reduces. Set aside.

Step 5: Make the dressing

Combine olive oil, minced garlic cloves, Dijon mustard, red wine vinegar, lemon juice, sea salt, and ground black pepper in a small bowl.

Step 6: Toss the rest of the ingredients

When 40 minutes are up, put roasted cauliflower and potatoes into a large bowl and add the finely chopped tender kale. Toss everything together until the greens begin to wilt.

Step 7: Add dressing, garnish, and serve!

Add dressing and stir to coat. Serve at room temperature topped with extra rosemary if desired, and salt and pepper to taste.

Expert Tips

Massaging the raw kale makes it more delicious, and easier to digest, softens its texture, and releases its bitter compounds
If you’re new to kale salad, or if your kale is especially tough or bitter, try mixing in a few handfuls of softer baby salad greens
Switch up potatoes by using red potatoes or tender sweet potatoes.
After cutting your cauliflower into uniformly sized florets, wash it well under cold running water. Be sure to rinse out all the little spaces where dirt can hide. Remove the excess water, but don’t worry about drying your cauliflower completely before roasting.
Be sure not to crowd your baking pan, otherwise, you run the risk of steaming your cauliflower rather than roasting it and you will end up with mushy and unevenly cooked pieces.
You can use a salad spinner to dry the kale completely.
