Roasted Vegetables Over Creamy Polenta

A light, summery dish pairing caramelized roasted vegetables with silky cornmeal polenta. Asparagus, zucchini, and red onion develop sweet, jammy edges in a hot oven, then finish with a bright red wine vinegar glaze. The creamy polenta base, enriched with skim milk and a whisper of herbs, provides a gentle canvas for the roasted vegetables. Perfect for vegetarian dinners, meal prep bowls, or as a simple side. This version keeps things lean while maintaining comfort-food appeal through technique and quality ingredients.

Tips
Don't skip the halfway stir during roasting. It ensures even caramelization and prevents burning on one side.
Whisk cornmeal into cold milk first if you prefer, then heat gently to avoid lumps. Constant stirring is non-negotiable for smooth polenta.
The vegetables release liquid as they cool; serve immediately or the polenta will absorb excess moisture and become dense.
Good to Know
Refrigerate leftovers in an airtight container for up to 3 days. Polenta will firm up; reheat gently with a splash of milk to restore creaminess.
Roast vegetables up to 8 hours ahead and store covered. Make polenta fresh just before serving, or prepare it ahead and reheat gently.
Serve immediately while polenta is warm and creamy. Pair with a crisp white wine or light salad.
Common Mistakes
Add cornmeal too quickly to avoid lumps; whisk slowly and steadily.
Stir polenta constantly to prevent sticking and scorching on the pan bottom.
Don't let roasted vegetables cool before serving; they'll release moisture and soften the polenta.

FAQ
Can I use fresh herbs instead of dried?
Yes. Use three times the amount: 1.5 teaspoons fresh basil or rosemary, added near the end of cooking to preserve flavor and color.
What if my polenta is lumpy?
Strain it through a fine-mesh sieve, pressing gently with a spatula. Or blend briefly with an immersion blender if you prefer a perfectly smooth texture.
How long can I store leftovers?
Up to 3 days refrigerated in an airtight container. Polenta hardens as it cools. Reheat gently on the stovetop or microwave, thinning with milk or broth as needed.
