How to Make Roasted Onions in Tomato Sauce

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. This step ensures even cooking and helps prevent sticking.

Step 2: Prepare the Onions

Toss those onion wedges with olive oil, salt, and pepper until they’re well coated. Arranging them in a single layer on your baking sheet allows them to roast evenly. This roasting process caramelizes the onions beautifully, bringing out their natural sweetness.

Step 3: Roast the Onions

Roast the onions for about 25-30 minutes, flipping them halfway through. You want them tender and charred on the edges—this adds depth to their flavor!

Step 4: Make the Sauce

While those onions are roasting away, sauté minced garlic in a skillet until fragrant. Then add your tomato sauce, lemon juice, and oregano. Let this simmer for about 3 minutes to marry those flavors together; this step is crucial as it enhances the overall taste of your dish.

Step 5: Combine Everything

Once your onions are roasted to perfection, add them directly into the warm sauce. Let them simmer together for another 5-8 minutes so that every bite is infused with that delicious tomato goodness.

Step 6: Serve and Enjoy

Finally! Serve this delightful dish warm alongside crusty bread, pasta, or your choice of protein. Don’t forget to sprinkle some fresh parsley or grated cheese on top if you like!

Enjoy every bite of these Roasted Onions in Tomato Sauce; I promise they’ll become a cherished favorite at your table too!
