We all have those nights when we’re scrambling to figure out what to make for dinner, right? Where you are digging through the refrigerator looking for groceries to somehow turn into a proper meal? That’s why this recipe is so awesome!

Even if you haven’t been to the grocery store lately, I’d venture to say that most of us have bags of frozen vegetables sitting in the freezer, making this an easy go-to side dish for any meal!

Why I love this recipe

  • it’s easy enough for the kiddos to help
  • frozen vegetables are frozen at peak ripeness so they taste great!
  • you can play with seasonings to make the roast vegetables your own

Step by step

  1. Preheat the oven with the baking sheet inside. This heats the baking sheet up so when you add your vegetables they start cooking immediately and helps reduce the “mushy” factor that frozen veggies can sometimes have.
  2. Toss the vegetables in a large bowl with a drizzle of olive oil, salt and pepper, and any other seasonings you want to use (see below).
  3. Spread vegetables evenly on the pre-heated baking sheet, being sure not to crowd them.
  4. Roast for 30 minutes, flipping halfway.

Tips for best results

Be sure not to crowd the veggies on the pan, it will result in them steaming instead of roasting and you’ll end up with a mushy texture end result.

Smaller, more delicate vegetables will roast faster than thicker cuts so adjust cooking times accordingly. Chopped broccoli florets, brussel sprouts, butternut squash, or cauliflower will take longer to roast than smaller cuts like green beans, peas, cut corn, asparagus, or sliced carrots.

Store leftovers in an airtight container in the fridge up to three days.

Seasoning ideas

I love that you can adjust the flavor to experiment and find what your family loves the most or what would compliment your main course perfectly.

  • Mrs. Dash
  • garlic powder and/or onion powder
  • chili powder
  • curry powder
  • sprinkle with Parmesan cheese after roasting
  • squeeze lemon juice over the vegetables after placing on the sheet pan
  • add soy sauce to the olive oil
  • serve with this garlic dijon sauce
