Start by gathering all your ingredients. Have your red onions sliced and garlic minced before heating anything. This organization will make cooking smoother, and you won’t find yourself rushing later.

In a large pan, melt the knob of unsalted butter with the olive oil over medium heat. The butter will add a creamy texture while the olive oil raises the smoke point. This combination helps sauté the onions evenly without burning.

Once you see the butter bubbling, toss in the sliced onions. Stir well, ensuring they are coated in the fat. Cook these onions gently, stirring occasionally. It might feel like a slow process, but patience is key here. You want those onions caramelized, not burnt.

After about 10-15 minutes, when the onions are softening beautifully, add the minced garlic and thyme. Cook for another 5 minutes. Here’s where the kitchen starts smelling heavenly. Stir occasionally to keep everything mingling.

Next, pour in the red wine vinegar and honey. The vinegar will add tanginess, while honey will boost that sweet flavor. Stir everything together, allowing it to bubble for a couple of minutes. This step balances the flavors, making them pop.

If you’re using smoked paprika or balsamic vinegar, add them now. Give it a good mix, and let everything simmer for an additional couple of minutes. You’ll see the consistency thickening beautifully.

Finally, taste your delicious onion mixture. Adjust for seasoning if necessary. Once it reaches the desired taste, serve it hot. Enjoy how these onions elevate your meal!
