Roasted Veggies with Balsamic Sauce & Grilled Polenta

Savory, Tangy & Melt-in-your-mouth Yummy!

About once a week, dinner here involves roasted veggies, grilled or breaded chicken and some kind of sauce or dressing.  I was craving a simple but tasty Balsamic Sauce and updated this recipe so that the Balsamic Sauce could be made separate and served on the side to accommodate all to the various tastebuds at the table.

This sauce is a must try! Balsamic vinegar is one of the easiest and yummiest ways to serve up super tasty veggies and this sauce is savory, tangy and melt in your mouth yummy!

Paired with warm roasted veggies and grilled polenta (I used pre-cooked  Ancient Harvest polenta), it’s super cozy and satisfying!

Here it’s served with blistered tomatoes, mushrooms and asparagus quickly. The flavor is insane!

If you eat dairy, would also pair well with some goat cheese. If you’re not a vegetarian, this pairs really well with grilled chicken.

  • 1 bunch asparagus trimmed
  • 1 pint grape tomatoes halved or whole (I prefer while when roasting)
  • 1 10 oz. container mushrooms sliced
  • 4 garlic cloves minced, divided

Balsamic Sauce (makes just under 1/2 cup -- double if everyone at the table is using the sauce)

  • 4 teaspoons olive oil
  • 4 tablespoons balsamic vinegar
  • 1 teaspoon corn starch
  • 1 tablespoon water
  • 3/4 teaspoon - 1 teaspoon brown sugar more to taste

1 tube pre-cooked polenta

Goat cheese for serving (Optional)



  • Slice polenta into 1/2 inch slices.
  • Heat an indoor grill pan, saute pan or outdoor grill over medium high heat. If using grill pan or sauce pan, spray pan with olive oil and place polenta in single layer on pan. If using outdoor grill, lightly spray or coat both sides of polenta with olive oil. Cook 5-7 minutes until outside crispy, flip and repeat. Set aside.


  • Preheat oven to 400 degree F and line 3 baking sheets with parchment paper.
  • One vegetable at a time, toss with olive oil, lay in a single layer on prepared baking sheet and sprinkle with salt.
  • Bake mushrooms and asparagus for 30 minutes or until tender and just crispy.
  • Bake tomatoes for 10 minutes or until blistering.

Balsamic Sauce

  • In a small bowl mix corn starch and water until combined.
  • In a small sauce pan, over medium high heat, stir in olive oil, vinegar, corn starch mixture and brown sugar. Bring to a boil then reduce to simmer and stir while sauce thickens. Sauce thickens very quickly. Remove from heat and place in a heat proof small serving bowl and stir once more to make sure well combined. Sauce will continue to thicken as it cools.
  • Serve sauce warm or room temperature.
