Step 1: Preheat oven to 400 degrees, wash and trim asparagus spears. Then place them in a 9 X 13 baking dish.

Is it important to trim fresh asparagus for this keto casserole?

Yes, the hard pale end of the asparagus lacks the moisture that the rest of the asparagus has, making it dry and wood-like. If you do not trim the asparagus, the whole stalk will become chewy, stringy, and hard to eat, but don’t worry, trimming asparagus is super easy!

How do I trim asparagus?

There are multiple ways to trim fresh asparagus. You can peel the bottom until the tough woody outside is removed, leaving the more tender juicy part of the asparagus. You can pinch the end part and bend until it snaps, or line all of your asparagus up on a cutting board and chop the ends off. Here are detailed steps if a visual is more helpful.

Heavy whipping cream, cream cheese, butter, and other seasonings in a silver pan ready to be made into creamy low carb sauce

Step 2: Add cream cheese, heavy cream, chicken broth, butter, garlic powder, and other seasonings to a saucepan. Turn stovetop onto medium heat, and stir until it’s combined.

Tip: If you do not have garlic powder on hand, 1/4 tsp is equivalent to 2 garlic cloves, similarily you can use 1 tsp of minced garlic.

Step 3: Simmer the cream sauce until the heavy whipping cream begins to reduce and thicken. Continue to whisk so that the sauce does not stick to the bottom of the pan.

Step 4: Add parmesan and Monterrey Jack cheese. Stir until the cheeses are melted, and the sauce is completely smooth.

Step Six: Pour the cheese sauce over the asparagus, then top with mozzarella cheese and crushed red pepper. This will add a slight kick to this asparagus casserole. Feel free to leave it out if you are serving little ones or are sensitive to spicy foods.

Step 7: Bake the casserole for approx 15 minutes then cover with bacon crumbles. If you prefer your asparagus to be crunchier, you may want to adjust the cooking time down.

Tip: When cooking bacon for this recipe, line a baking sheet with parchment paper before putting bacon on the sheet. Then place in the oven at 400 degrees for 15-20 minutes or until it reaches the desired amount of doneness. By placing parchment paper over the baking sheet, you significantly reduce the amount of cleaning needed.

You can also follow this quick and easy recipe to cook bacon in the microwave if you do not have time or want to bake it!

Is asparagus keto?

Yes! One cup asparagus contains 7 grams of carbs and 3 grams of fiber, making it only 4 grams of net carbs per cup.

If I have thinner asparagus is the bake time affected?

It comes down to preference and how crunchy or tender you like asparagus. However, thinner asparagus is going to cook faster than thicker asparagus, so you may need to reduce the baking time by a couple of minutes.

What do I eat with this?

This keto asparagus casserole pairs great with the following:

Can I use other vegetables instead of asparagus in this recipe?

Yes, you can use whatever type of keto-friendly veggie you’d like! Perhaps try fresh green beans, zucchini, cauliflower, or Brussel sprouts for a nice change of pace.

Can I make this ahead?

This asparagus side is easy to make. You can also make it in advance by following all of the steps in the recipe card except baking it in the oven. When you are ready to bake it, warm it slowly by putting it in the oven while the oven is preheating then following the remaining steps in the recipe card below. Warming it slowly is very important to keep the sauce from separating. It may take a few extra minutes to bake since it has been refrigerated.

  1. This was a delicious addition to my dinner of peppercorn crusted steaks, salad and crusty bread! I left the bacon off because I was basically too lazy but even without the bacon the recipe turned out fantastic. It complimented the rest of the meal perfectly. I will make this again….. perhaps next time I’ll rustle up more energy and add in the bacon.

      Seriously…so good. Even better the next day. I’m actually on Day 3 in a row and I’m still thinking about it. The first time, I made it as directed and couldn’t wait to make it again. The second time, I forgot bacon and used used leftover ham and it was also very good. I also think this would be great with chicken, maybe doubling the sauce. I’m looking for more Kasey recipes as we speak 🙂

    I just made this yesterday for lent and it was amazing. That sauce is insanely good and pulls the whole dish together. I will be making this again.

    Made last night and got rave reviews. I had 2 very large bunches of asparagus so I did double the sauce recipe but did not use double the salt. Due to the amount of asparagus should have cooked it a little bit longer as some was still a little crunchier than I’d like but will do that next time. Great recipe and looking forward to left overs for lunch.

    1. Mmmm, sounds so good!! As a super busy mom of 4, I LOVE leftovers. lol!! Glad you enjoyed this recipe!

    1. Awe, so glad you loved it, Jolanda! Thanks for visiting and leaving a review!

  4. Hi. I’m making roasted cornish game hens for Xmas. Do you think this would pair well with a roasted chicken. It looks fabulous and would love to have it as one of my Xmas side dishes. Thank you.

    1. I don’t have experience with cooking Cornish game hens but from what I have heard the taste difference between it a chicken is minute possibly non-existent. Take that for what it is worth. I may not understand your question about having the Cornish game hen as a side dish though. I think it would be considered a protein just like your roasted chicken.

  5. 5 stars
    Creamy and flavourful. We went all out this Christmas with gourmet dishes and this was a nice accompiment. Will definitely make again. Thank you!
