Ingredients
To make these fabulous Asiago Roasted Onions, here’s what you’ll need:
- 4 large onions: Select sweet onions like Vidalia for best results.
- 2 tablespoons olive oil: Extra virgin olive oil adds a robust flavor.
- 1 cup heavy cream: Look for fresh cream for the best texture.
- 1 cup Asiago cheese, grated: Aged Asiago enhances the flavor, so choose a good quality brand here, like BelGioioso.
- Salt and pepper to taste: Use sea salt for better flavor.
- Fresh herbs for garnish (optional): Chopped parsley adds a pop of color and freshness.
Prep Notes: Make sure your heavy cream is at room temperature for smooth blending!
Step-By-Step Instructions
Ready to get those delicious Asiago Roasted Onions cooking? Let’s dive in!
Preheat your oven to 400°F (200°C): Get it hot and ready for roasting—this is key for caramelization!
Peel the onions and cut them in half: I like to use a sharp knife for clean cuts.
Drizzle olive oil over the onions and season with salt and pepper: Make sure to coat every inch for maximum flavor. Place them cut side down on a baking sheet lined with parchment paper for easy clean-up.
Roast the onions in the preheated oven for about 30-35 minutes: Watch for the outer edges to turn a beautiful golden brown—the sweet aroma will start filling your kitchen.
In a saucepan, warm the heavy cream: Use low heat to avoid scalding. Stir in the grated Asiago cheese until melted and creamy.
Once the onions are done roasting, remove them from the oven: Carefully pour the creamy Asiago sauce over the onions. Don’t skip this!
Return to the oven for an additional 5-10 minutes: You want that cheese to be bubbly and slightly golden. Yes, that’s the good stuff!
Garnish with fresh herbs if desired: Fresh parsley is my go-to—it adds a lovely color and brightness.
Serve warm: Trust me; you want to enjoy these while they’re warm and gooey!
Chef’s Tips
- Avoid Common Mistakes: Ensure the onions are well-coated in olive oil; otherwise, they might dry out.
- Professional Techniques: For added depth, consider sautéing some garlic in the olive oil before drizzling it over the onions.
Expert Tips & Tricks
Want to take your Asiago Roasted Onions to the next level? Here are my top tips!

Troubleshooting: If your cheese doesn’t melt smoothly, ensure your cream is warm enough and stir continuously as you add the cheese.
Scaling the Recipe: You can easily double or halve the recipe based on the number of guests!
