I made half a recipe using 2 cups of leftover roast chicken cut into cubes. Subbed gruyere cheese that I had leftover from another recipe for the gouda. Combined the cooked chicken and asparagus with the sauce in the skillet, then dumped into a greased 8 x 8 casserole, topped with the additional cheese and baked per the recipe. Turned out delicious! Leftovers were just as good. A recipe that can be made with either raw chicken or leftovers from a roast is a definite winner in my book!
Kori
That sounds fantastic. I love how you adapted it by using leftover roast chicken. It's such a great shortcut, and gruyere is a perfect swap for gouda. Thanks for sharing!
Paula
I think I might try making this with boneless chicken thighs cut up. I allways find chic breast a little dry. Other than that this sounds fantastic! I hope it travels well cause I'll make it dump it into my 9/13 dish and take it to my in laws & reheat it there.
Kori
That sounds like a great plan. Chicken thighs will work really well here — they tend to stay a bit juicier than breasts, so that’s a nice swap. Casseroles like this are often great for bringing to gatherings since they reheat well and hold their flavor and texture.

This is the second time I've made this recipe. My hubby and I both love it! l am a bariatric patient so I have to eat high protein/low fat/low carb. In order to make this fit my restrictions, I adjusted the recipe just a bit:
• I used an olive oil spray just to coat the bottom of my pan to brown the chicken rather than the butter
• I cut the amount of butter in half and used that to saute the onions and mushrooms
• I used evaporated whole milk instead of heavy cream (about 1/3 the fat). The sauce would break when adding the lemon juice, if using fat free
• I used a reduced fat cheese.
The result was a creamy, cheesy, yummy casserole with 459 calories, 10 net carbs, 50 grams protein, and 23 grams fat!

Oh this is a good one! I made it according to your directions for one pan instead of dirtying a 9x13, came out perfect! 2nd time I made it, which was tonight I forgot the avocado mayo, but it came out just as delicious! Thank you so much this is going to be a regular dish at our house!
Kori
I’m so glad you enjoyed it. I love that you did the one-pan version too — fewer dishes is always a win. And it’s great to hear it still turned out delicious even without the avocado mayo. Thanks so much for coming back to share, and I’m happy it’s going into your regular rotation.
Paul
Made this today and followed the recipe exactly. We loved it but next time I won’t precook the asparagus (found it was overcooked) and I found the sauce very runny so next time I will make a rouge with flour and butter after the mushrooms and onion are cooked to make it a bit thicker. Other than these 2 adjustments the flavour was stellar and it was delicious
Brenda Shaw
Making this tonight. Was hoping to watch the video but it’s not working. Wish me luck!
Claudia
I made this tonight. Was very watery.
Thought about adding cornstarch. But wasn’t sure if to add it to the sauce before combining with the chicken, or if it could be done after cooking everything.
Kori
I’m sorry it turned out watery — that can definitely happen depending on the chicken and asparagus since they both release moisture as they cook. You can absolutely thicken it with a little cornstarch. I’d recommend mixing 1–2 teaspoons cornstarch with a tablespoon of cold water to make a slurry, then stirring it into the sauce and letting it simmer for a few minutes until it thickens.
Charlie
I went a little rouge on this recipe. We are short on heavy cream, so I skipped the whole heavy cream mixture portion and used a can of cream of chicken soup instead. I added about a cup of uncooked rice that I let soak for about 15 minutes prior to adding to the dish. So basically I cooked the chicken, asparagus (stemming in microwave is brilliant), mushrooms, onions (adding 1/2 tablespoon of minced garlic to the sauté). Then added all of that to the dish with about 1.5 cups of chicken broth, one can of cream of chicken soup (with herbs), 1 cup soaked rice, 1(ish) tablespoon of Italian seasoning. Mixed it up good and cooked for 30 minutes. Then took that out to mix again, topped with French’s fried onions and a bit of fresh shredded Parmesan cheese.

This is fabulous!!! I used what I had, 5 cheese Italian cheese, Soooo good, but next time will make pasta to go with it. *****
Wilma Witte
I made this for my daughter and I. We both thought it was delicious even with the changes I made to make it dairy free for her. I used dairy free milk and dairy free cheddar cheese ( I haven't found any other dairy free cheese except mozzarella)
We are definitely making this again.
seekinggoodeats
Thank you, I'm super happy you enjoyed this and that you tried dairy free substitutions. I will make it this way next time! 🙂
KT
I made this tonight and it was delicious! I used a bag of Swiss/Gruyère cheese and added some Ritz crackers and melted butter on top- it was SO good! (Can’t miss with butter, right?😉). I will definitely make this again!
Thank you for a keeper recipe!

This has to be one of the best casseroles I've had in a long time! I'm a bariatric patient so my requirements aren't *quite* keto (high protein, low carb, but also low fat) so I made a few minor adjustments to make this fit into my dietary guidelines.
Instead of 4 tbsp. of butter, I only used 2 tbsp. I used evaporated whole milk (same amount) instead of the heavy cream to reduce the fat without removing it completely which kept my sauce from breaking. I also used light mayo. Since I only had Duke's light mayo on hand, I left out the lemon juice. To me, Duke's is QUITE tangy and I was afraid adding the juice would be overwhelming.
While I know changes to the recipe can affect the results, I'm pleased to say that this WILL be made regularly! My carnivore fiancé even said he'd even like more asparagus in it. (To be fair, when I snapped my asparagus to remove the woody ends, it did reduce the amount so I might double it next time.) I was also thinking about trying this with cut haricots verts instead of asparagus. Thanks so much for a recipe that feels indulgent but still safe for me to eat!
