Key Ingredients for Sour Cream and Cheddar Roasted Onions
- 4 large yellow onions, peeled and quartered
- 4 tablespoons olive oil
- Salt and pepper, to taste
- 1 cup sour cream (or plain yogurt for a lighter option)
- 1 cup shredded cheddar cheese (sharp or mild, depending on your preference)
- 2 tablespoons fresh chives, chopped (optional, for garnish)
These ingredients are straightforward and easily accessible, making it an excellent choice for any home cook.
Step-by-Step Instructions
- Preheat your oven to 400°F (200°C). This is the magic number for roasting, allowing the onions to caramelize nicely.
- Prepare the onions: In a large mixing bowl, toss the quartered onions with olive oil, ensuring they are well-coated. Sprinkle them with a generous pinch of salt and pepper.
- Spread them out evenly on a baking sheet lined with parchment paper. This will help prevent sticking and make clean-up a breeze.
- Roast the onions in the preheated oven for about 30 minutes or until they are golden brown and tender, giving them a gentle stir halfway through to ensure even cooking.
- Remove from the oven and immediately dollop sour cream over the hot onions, allowing it to melt slightly into the grooves.
- Sprinkle with cheddar cheese and return to the oven for an additional 5-10 minutes, until the cheese is melted and bubbly.
- Serve piping hot, garnished with fresh chives if desired.
Top Tips for Perfecting Sour Cream and Cheddar Roasted Onions
- If you want to add a little extra flavor, try using different cheese varieties like mozzarella for a milder taste or pepper jack for a little kick.
- To save time, you can slice the onions ahead of time and store them in the refrigerator until you’re ready to roast.
- Make sure to watch closely during the last few minutes of roasting after adding the cheese. Ovens can vary, and you don’t want the cheese to burn!
Storing and Reheating Tips
To store any leftovers of your Sour Cream and Cheddar Roasted Onions, place them in an airtight container in the refrigerator, where they’ll keep for about 3-4 days. When you’re ready to enjoy them again, simply reheat in the oven at 350°F (175°C) for 10-15 minutes, or until warmed through. If you want to freeze them, you can do so in an airtight freezer bag, and they will last for up to three months. To reheat from frozen, allow them to thaw overnight in the refrigerator before warming them in the oven.
