Garlic Galore: Preheat your oven to 375ºF. Slice off the tips of the garlic heads to expose the cloves. Place them cut-side-up in a baking dish, drizzle each with a smidge of olive oil, and roast for 20 minutes.

Flip and Roast Some More: Turn the garlic heads over, and roast them for another 20 minutes. Let them cool for about 10 minutes post-roasting.

Garlic Harvest: Once they're cool enough to touch, squeeze each head to release the softened cloves.

Flavor Fusion: Crank up the oven to 400ºF. Combine the roasted garlic and softened butter in a bowl, mixing until well blended.

The Cheesy Choir: Add mozzarella, cheddar, parmesan, salt, pepper, and parsley to the butter mixture. Stir until everything's singing the same delicious tune.

Toast Prep: Coat a baking sheet (or two, depending on their size) with non-stick spray. Lay out the Texas toast slices.

Generous Slathering: Use a knife or spatula to spread roughly ¼ cup of your cheesy concoction on each bread slice.

The Grand Bake: Insert the prepared slices into the 400ºF oven. Bake for 7-10 minutes, or until the edges are golden and the cheese has melted into divine gooeyness.

Rest and Rejoice: Let them sit for 3-4 minutes. Dig in while they’re still warm!
