On a baking sheet lined with foil, place asparagus down in neat-ish rows (see pictures for reference). Sprinkle the minced garlic evenly on the asparagus, and mix around a bit with a spoon or fork. Squeeze the ends of the lemon over the asparagus, and lay down the slices on top of the asparagus.
Season asparagus with salt and pepper. I used about a 1/4 tsp of each, but you can add as much or as little as you like.
Roast in the oven for 15 minutes. When done, let cool and set aside.
Lemony Herb Pasta
While the asparagus is cooking, cook the pasta according to the manufacturer's instructions.
When done, drain and place pasta back in pot.
Add in olive oil (between 2-4 tbsp, as much as you like), minced garlic, salt, pepper, dried herbs, and lemon juice. Mix until evenly combined. Taste and adjust seasonings if necessary.
