In a small saucepan, heat the olive oil (1/4 cup), garlic (4-6 cloves), lemon zest (1 teaspoon), oregano (1 teaspoon), and red pepper flakes (1/4 teaspoon) over low heat just until the garlic starts to become golden. Remove pan from heat and cool for about 10 minutes. (Garlic will continue to brown a bit more)
Preheat oven to 425ºF (218ºC).
On a rimmed baking sheet, toss asparagus(2 pounds) with infused oil until well coated. Arrange asparagus into a single layer, using a second baking sheet if necessary. Sprinkle with salt and pepper. Toss feta (1/2 cup) evenly over the asparagus.
Roast asparagus in the preheated oven for 10-12 minutes until it reaches the desired tenderness.
Cut lemon in half, and squeeze lemon over asparagus and serve.
Notes
Coat It! It’s important that all the asparagus gets well coated with the infused oil so make sure you toss it well and spread the garlic out a bit, don’t just pour it on top of the asparagus.
Single Layer: I toss the whole thing right on the baking sheet I’m going to use then straighten the asparagus out into a single layer.
Use 2: You may need to use 2 baking sheets in order to get a single layer depending on the thickness of your asparagus. You don’t want to crowd the asparagus or it won’t roast properly.
Lighten Up! Also, if you’d like to lighten the dish up a bit, you can use a portion of the oil, say even half of it, not the entire amount. It will still be amazing!
