You can cook ‘em, steam ‘em, saute ‘em, bake ‘em and grill ‘em but, until you have roasted veggies, you are missing out.
Roasting vegetables mellows the flavor. The dry heat of the oven caramelizes the natural sugars in vegetables which brings out an amazing depth of flavor. There are hardly any veggies that don’t benefit from this manner of cooking. Surprisingly, even salad greens like romaine can be roasted and transformed into more complex and intensely-flavored versions of their fresh selves.
The best part is that it is so simple and hands-off. All you really need is a good coating of oil and a little salt and pepper. Unlike boiling, which sometimes will leach nutrients from foods, roasted veggies will retain their heart-healthy fiber as well as their vitamins and minerals for fighting disease.
Done right, they will be crispy on the outside and fluffy on the inside. Fall and winter is the perfect time to engage in this method. Whether raising the vegetables yourself or buying, the season’s end is abundant with different varieties of root veggies among others. It is also cooler so running the oven may actually feel good.
HOW TO ROAST. All root vegetables lend themselves well to roasting and many others do too. Which ones to include is all a matter of personal taste. However, depending on their density, they have different roasting times. So, either choose ones with like times so they finish together or put the ones with the longer roasting times in first and add others later.
Be sure to cut them in uniform sizes so they roast evenly. Coat the pieces in oil and lay in a single layer on a baking sheet. For easier cleanup, you may want to use parchment paper. Sprinkle with salt and pepper and roast at a temperature anywhere between 400*F and 500*F. Temperatures any lower than that will only bake them and they will not be caramelized.
*Avocado oil has the highest smoke point of the oils at 520*F. It is also the most neutral of all oils since it has no flavor of its own, making it an excellent choice to pair with any food and all flavorings.
*Coconut oil has a smoke point of 450*F., which is probably the maximum temperature that any recipe will call for when roasting. It adds a mildly sweet flavor and is a little trickier to work with since it is a solid below 78*F.
*Ghee has a smoke point of 482*F and is made by clarifying butter which removes the proteins but leaves the nutrients. It has a heady, butter-type flavor which is earthier and more pungent.
*Olive oil. This is probably the most popular choice with a smoke point anywhere between 375*F and 405*F. It has a high resistance to oxidative damage which means its fats don’t turn rancid, even at high temperatures. Olive oil usually works good at 400*F. Its flavor is not as neutral as avocado, but you can use this to your advantage to make veggies shine.
When choosing oils for roasting, the two main considerations are flavor and smoke points.
ROASTING TIMES. Again, these are general guidelines, it all depends if you like yours just fork tender or a little more done. A little experimentation will yield roasting times that are good for you.
*Thin and soft vegetables like yellow squash, zucchini, peppers, beans, asparagus and tomatoes only take between 10 and 20 minutes.
*Greens like kale, collard and mustard greens are done within 6 to 10 minutes.
*Onions are between 30 and 45 minutes.
*Mushrooms take between 20 and 40 minutes.
*Winter squash and root vegetables like carrots, potatoes, sweet potatoes, turnips and beets are anywhere between 30 and 60 minutes.
SPICES. Don’t be afraid to experiment. There are so many herbs and spices, each lending its own flavor to the veggies. Start with the basics of salt and pepper then try your favorite flavorings. Just be careful and not try too many different ones at the same time or you won’t know which combinations you prefer. One of my favorite combos is rosemary and thyme. To make it even more complicated, different herbs taste different on different veggies.
Once you have found your favorited seasonings, don’t be afraid to change it up a bit. Add a little bacon for some protein once in a while (bacon makes everything better, right!). Try adding some marinated steak strips when the veggies are nearly done.
You can even cheat if you like a little sweetness. Add a couple tablespoons of honey or maple syrup to enhance the natural sugars.
Always remember to go big with your roasting pan. Choose a pan with low sides and one where you can spread them out so they are not touching. You want the heat to get to all the edges. Overcrowding leads to a steaming effect, trapping moisture instead of evaporating it.
Another common mistake is resisting the urge to lower the heat. If you don’t keep them in the 400*F range, the veggies will only bake instead of roast and the caramelized effect will be lost.
There just aren’t any negatives to roasting veggies. This method is easy, quick, good for you and has a decadent flavor. They can be doing their thing while you are busy with the rest of the meal. What’s not to like!
