In a small bowl, mix together olive oil and garlic; let it infuse for 4 to 5 hours at room temperature.
Preheat oven to 300ºF.
Cut a baguette in half, then half and then in cubes; place in a big bowl.
Using a fine sieve, strain oil infusion over the bread cubes, pressing garlic with the back of a spoon.
Toss very well with a spatula until the bread is completely coated.
Mix ½ cup of cheese with thyme, oregano, basil, cayenne and black pepper; toss well.
Place seasoned bread cubes on a baking sheet lined with a silicone mat or parchment paper in a single layer and transfer to the preheated oven; bake for 15 minutes.
Remove from the oven and toss them again; bake for another 15 minutes.
Remove from the oven (they won’t be hard yet) and put them close together in the center of the baking sheet. Sprinkle on the remaining Parmesan cheese.
Return to the oven once again and bake until nice and crispy, about 13 to 15 minutes.
Store them in a re-sealable plastic bag when they are completely cool.
