Remove the 1/2 cup (1 stick) butter from the fridge at least 30 minutes before starting so it becomes soft and spreadable.

Place the softened butter in a medium bowl. Add 1/4 cup olive oil, 1 teaspoon Italian seasoning, 1/2 teaspoon garlic powder, 1/4 teaspoon salt, and 1/4 teaspoon pepper.

Using an electric hand mixer, start on low speed to combine the ingredients, then increase to medium. Mix until the mixture is smooth and has a fluffy, whipped-butter texture, scraping down the bowl sides with a spatula as needed (about 1–3 minutes depending on butter softness).

Taste the butter and, if desired, add a little more salt or pepper to suit your preference; briefly mix again to incorporate any additions.

Transfer the spreadable butter to a clean jar or airtight container. Refrigerate for storage.

Store in the fridge; it will be spreadable straight from the fridge and will last at least 2–3 weeks. If you want it softer before using, let it sit at room temperature for a few minutes.
