Preheat Oven: Preheat your oven to 180°C (350°F). Line a baking tray with parchment paper.
Prepare Garlic Butter: In a mixing bowl, combine softened butter, minced garlic, parsley, and sea salt. Mix well until smooth.
Slice Bread: Using a serrated knife, slice the gluten-free baguette in half lengthwise.
Spread Mixture: Evenly spread the garlic butter mixture over the cut sides of the bread.
Add Cheese (Optional): Sprinkle grated parmesan and shredded mozzarella over the top.
Bake: Place bread halves on the baking tray and bake for 12-15 minutes until golden and crispy.
Broil for Extra Crunch: For an extra crispy finish, broil for 1-2 minutes, watching closely to prevent burning.
Serve: Slice into portions and serve warm. Enjoy!
