This garlic Parmesan asparagus is the kind of effortless side that makes a weeknight keto dinner feel like a steakhouse. A quick sear keeps the spears bright and snappy while butter, golden garlic, and a finish of lemon and Parmesan do all the heavy lifting.
Ingredients
- 1 lb fresh asparagus, woody ends trimmed
- 2 tablespoons unsalted butter
- 1 tablespoon extra-virgin olive oil
- 4 cloves garlic, thinly sliced
- 1/4 cup grated Parmesan cheese
- 1 tablespoon fresh lemon juice
- 1/2 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
- 1/4 teaspoon red pepper flakes (optional)
- 1 tablespoon chopped fresh parsley, for garnish
Instructions
- 1
Trim the tough woody ends from the asparagus (about the bottom 1 to 1.5 inches snaps off naturally). Pat the spears dry with a towel so they sear instead of steam.
- 2
Heat the butter and olive oil in a large skillet over medium heat until the butter is melted and foamy.
- 3
Add the sliced garlic and cook for 30 to 45 seconds, stirring constantly, just until fragrant and pale gold. Do not let it brown or it will turn bitter.
- 4
Add the asparagus in a single layer along with the salt, pepper, and red pepper flakes. Cook for 6 to 8 minutes, tossing every couple of minutes, until the spears are bright green and crisp-tender.
- 5
Turn off the heat and stir in the lemon juice. Sprinkle the Parmesan over the top and toss so it lightly melts and clings to the spears.
- 6
Transfer to a serving platter, scatter with fresh parsley, and serve warm.
Tips & notes
- Thinner pencil asparagus cooks in about 5 minutes; thick spears may need the full 8. Adjust so they stay snappy, not mushy.
- Swap the Parmesan for nutritional yeast and the butter for more olive oil to make it dairy-free and vegan; net carbs stay about the same.
- Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a hot skillet for 2 minutes to revive the texture rather than microwaving.
