Preheat the oven to 425 degrees. Using a small food processor or immersion blender, blend the olive oil, garlic, balsamic vinegar, Italian seasoning, salt, and pepper until smooth. (Alternatively, mince the garlic as fine as possible and whisk together the ingredients.)
3 Tablespoons olive oil or avocado oil, 10 cloves garlic, 1 1/2 teaspoons balsamic vinegar, 2 teaspoons Italian seasoning, 1 1/2 teaspoons Morton kosher salt*, freshly ground black pepper
Add about two-thirds of the garlic oil mixture to a large mixing bowl with the potatoes. Toss well.
1 1/2 pounds red potatoes, cut into 1-inch pieces*
Line a large baking sheet with parchment paper. Add the potatoes in a single layer. Bake for about 20 minutes.
While the potatoes bake, toss the asparagus with the remaining garlic oil mixture.
1 pound asparagus, trimmed & cut into 2-inch pieces
Add the asparagus to the sheet pan. Sprinkle the potatoes and asparagus with the parmesan.
1.5 ounces (1/2 cup) parmesan cheese, shredded
Bake for an additional 15 minutes or until the vegetables are cooked to your liking.
