3. Step-by-step Instructions
Step 1: Prepare the Onions

Start by slicing your onions into thin, even slices. This will help them cook uniformly and caramelize perfectly. Aim for about ¼-inch thickness to ensure they cook down nicely. Using a sharp knife will also make this task easier and safer. Remember, the more uniform the slices, the more evenly they will cook, contributing to the best caramelized onion butter possible. Before you start cooking this onion butter recipe, make sure you have all your ingredients prepped and ready to go.
Step 2: Cook the Onions

In a large skillet over medium heat, melt the butter. Add the sliced onions, salt, and sugar, and stir them well. Cook for about 20–25 minutes, stirring occasionally to prevent burning, until the onions turn a deep golden brown and are soft. The sugars will caramelize, lending that delicious flavor! Patience is key here; don’t rush the process. If the onions start to stick to the pan, add a tablespoon of water to deglaze the pan and keep them cooking evenly. This step is crucial to achieving the rich, sweet flavor that defines a truly remarkable caramelized onion spread.

Step 3: Create the Onion Butter

Once the onions are caramelized, lower the heat and mix in the garlic powder if using. Let it cook for an additional minute, allowing the garlic to infuse its flavor into the onion butter recipe. Then, transfer the mixture to a bowl and let it cool slightly before serving. For a creamier texture, you can use an immersion blender to lightly blend the mixture until it reaches your desired consistency. This buttery caramelized onion spread will be a highlight in your kitchen! It’s perfect on a sandwich from the lunch category.
Step 4: Store and Serve

Transfer the caramelized onion butter spread into an airtight container and refrigerate. This spread can be kept for up to one week, and its flavors will deepen over time. When ready to serve, spread it on warm bread, top your steaks, or mix it into pasta for a decadent treat! Consider adding a dollop to Roasted Garlic Mashed Potatoes for an added layer of flavor.
4. Storage Tips
To preserve the freshness of your caramelized onion butter, store it in an airtight container in the refrigerator. You can also freeze it in smaller portions for later use, ensuring you always have a flavorful spread on hand! If freezing, consider using ice cube trays for convenient portioning.
