Start by preheating your oven to 300°F. Line a rimmed baking sheet with parchment paper so the pretzels don't stick as the butter bakes into them. This low, slow temperature is key to toasting the seasoning without burning it.
Melt your butter in the microwave or on the stovetop until it's fully liquid. I like to let it cool for a minute so it doesn't clump the seasoning when mixed. This small pause makes the coating far more even.
Place your pretzels in a large mixing bowl, then pour the melted butter directly over them. Stir gently but thoroughly so every pretzel gets a light, even coating. Don't rush this step, uneven coverage means uneven flavor later.
Sprinkle the everything bagel seasoning and garlic powder over the buttered pretzels. Toss again until the seasoning clings to every piece, not just the ones on top. This is where all that signature flavor gets locked in.
Pour the seasoned pretzels onto your prepared baking sheet in a single, even layer. Bake for about 10 minutes, stirring once halfway through so they toast evenly. You'll know they're ready when the butter looks fully absorbed.
Let the pretzels cool directly on the baking sheet before touching them. They'll be extremely hot and a bit soft straight out of the oven, but firm up as they cool. Waiting here is what gives you that satisfying crunch.
