The title says it all: Sheet Pan Simple Roasted Vegetables with Herb Sauce. This can be easily made as a side dish or as a healthy appetizer. For the simple and truly tasty sauce, I’m using my favorite ingredients: fresh herbs.

Pouring herb sauce over roasted asparagus

Spring is just around the corner and I’m already seeing in-season veggies in the grocery stores and farmers markets. For this recipe, I chose 4 of my favorite vegetables – asparagus, leeks, cauliflower and carrots. Of course, you can use a selection of your own 4 favorites as there are so many choices.

The herb sauce for the vegetables is vegan/plant-based, gluten-free and dairy-free and can be used as a dip, marinade or served over chicken or fish.

The beauty of a dish like this is that it is interchangeable when it comes to the vegetables. This way you can use fall/winter or spring/summer vegetables because the sauce will bring out the true flavor of the veggies, no matter which ones you choose!

I always say roasting vegetables is the best way to bring out their natural sweetness and the tip to getting them all to cook at the same rate is cutting them all the same size. Before roasting,

the vegetables get simple seasoning with oil and salt

Do you cover vegetables when roasting?

No! If you cover them, they will steam and not roast and there goes all that extra flavor.

What herbs go with vegetables?

I would say all of them. Basil, rosemary, mint, tarragon; the list is almost endless.

What oil is best for roasting vegetables?

Any light colored oil because they have a higher smoking temperature (which means they can withstand more heat without smoking). Vegetable, canola and grapeseed are all good choices.

The sauce can be made all year round because of the herbs that are used – basil, mint and chives are available 365 days of the year. With well-rounded flavors and a little sweetness from fresh dates and a tangy freshness from fresh lemon juice and zest, this sauce is so versatile you can also serve it over chicken or fish.
