I always love it when simple, elegant, and delicious collide. You are going to fall in love with this easy to make Keto Asparagus recipe. Crisp tender asparagus is seasoned and cooked perfectly. This finishing touch is a sprinkle of Parmesan and a drizzle of lemon juice.
It comes together without a lot of fuss and works just as well as a holiday side as it does on a busy weeknight. I think you will agree that this one is a keeper!

I didn't grow up eating asparagus and used to think I didn't like it.
I was traumatized in college by a friend who invited me over for dinner and proceeded to serve asparagus from a can.
Years later, I was coaxed to try a bite of asparagus at a restaurant.
It was nothing like what I'd had before. It was crispy, crunchy, and above all, tasted fabulous!
Since then, I make dishes like this Keto Asparagus regularly. I love that it only takes minutes to cook!
These days, I would go so far as to say I love asparagus.
It is the perfect low-carb and healthy side dish for those nights when I don't have a plan.
Keeping recipes like this one in my back pocket make sticking to a keto diet so much easier.
Frequently Asked Questions
Yes! Asparagus, like all other green vegetables, are a fantastic addition to your ketogenic diet.
One spear has just .3g of net carbs, meaning it would be hard to over-do the carbs when choosing asparagus as your side.
It is a fabulous side for steak (use this marinade), and works equally well with roasted chicken. I also love it with Keto Chicken Parmesan. Cooled roasted asparagus is a great addition to a salad.
It is an excellent source of probiotics, which help to feed the friendly bacteria in your gut. Additionally, it is a good source of vitamins A, C, E, K, and B6. It is an alkaline food, which is especially important to include in a keto or low carb lifestyle.
While both thick and thin asparagus is sweet and grassy, opt for thicker asparagus for this recipe. Thick spears will stand up to the heat better, and you won't have to worry as much about overcooking.
Look for spears where the bottom is still moist, and the tops are tightly closed.
When you get asparagus home from the grocery store, go ahead and trim the ends off. Fill a mason jar with an inch of water, and place the spears in it like you would flowers. Cover with a clear plastic bag.
It is a matter of personal preference. The thicker asparagus that I recommend you use for this recipe will have a woody base. Some people suggest that you break the bottom off at its natural breaking point.
This practice, while effective, causes a LOT of waste. For the sake of my grocery budget, I like to cut off the bottom inch and then peel the bottom half as necessary.

How to Make Low Carb Asparagus
First, preheat. You can make this recipe in the oven or the air fryer. To make Keto Air Fryer Asparagus, preheat your air fryer to 400 degrees. If using an oven, preheat to 420 degrees.
Next, trim the ends off the bottom.
Mix the oil and seasonings next. In a small bowl, mix the olive oil, garlic powder, salt, and pepper.
Toss - Place the vegetables in a bowl and pour the olive oil mixture over it.
Cook - Next, arrange in a single layer in an air fryer basket or on a parchment-lined baking sheet. Cooking time in the air fryer will be between 5 to 11 minutes, depending on the desired doneness. For the oven, the time will be from 6 to 13 minutes.
Transfer the cooked veggies to a serving platter. Squeeze fresh lemon juice over the vegetables and sprinkle with Parmesan cheese. (If desired, you can melt the cheese first and then transfer to a serving platter before drizzling with lemon juice.)
