First, break up the pasta.
Place the brittle vermicelli or fideo in a large zip-top bag and gently beat it with a rolling pin, or simply crush it between your hands directly over your pot to break it into smaller, bite-sized pieces.
Heat the olive oil in a large, deep skillet or Dutch oven over medium-high heat.
Once the oil is shimmering, add the broken pasta and minced garlic.
Season generously with salt and pepper.
Cook, stirring frequently, for 5 to 10 minutes. You're looking for the pasta and garlic to become beautifully toasted, golden brown, and incredibly fragrant.
Don't rush this step—it builds the foundational nutty flavor of the dish!
Carefully pour in 5 cups (1200 ml) (about 1. 2 L) of the warm vegetable stock and bring the mixture to a boil.
Reduce the heat to a simmer and cook, stirring occasionally, for about 10 minutes. The pasta will absorb most of the liquid. If the mixture looks too dry before the pasta is tender, add the remaining cup of stock.
Taste the pasta to check for doneness. If it's still a bit tough, cook for another few minutes.
Once tender, remove from the heat.
Adjust the seasoning with more salt and pepper if needed.
To serve, ladle the garlicky fideo into bowls and finish with a generous sprinkle of grated Parmesan cheese and fresh parsley.
Enjoy immediately!
