Keto Zucchini Au Gratin Casserole

When the only side dishes you’ve really eaten on a regular basis involve potatoes or pasta and you then switch to Keto or low carb, it can be hard to figure out what sides you CAN eat. Since my husband is a non-veggie eater, I just make sure I make plenty of the main course for him since he is more carnivore Keto. I, on the other hand, LOVE veggies – BUT I get tired of eating steamed broccoli or cauliflower all the time. I mean, who wouldn’t?? It becomes so monotonous.

So what else can you make? Well – PLENTY! There are a million and one things you can make. You just have to learn what your Keto friendly options are and figure out different ways to make them – and there are a LOT!

Zucchini is one of the most versatile vegetables in my opinion and when you add cheese – well, ’nuff said!

I love simple recipes and I love casseroles – which leads me to this Keto Zucchini Au Gratin casserole. You are basically layering veggies and cheese and pouring a creamy sauce over it. The result is cheesy deliciousness! I love all the yummy browned cheese on the top

Part of the simplicity of this dish is that there aren’t very many ingredients to it. They include:

  • zucchini
  • onion
  • pepper jack cheese
  • butter
  • garlic powder
  • whipping cream
  • xanthan gum
  • salt and pepper if desired

That’s it!!

It’s just as easy to throw together too. The most time consuming part is cutting the vegetables. You can put the whole dish together in about 5 minutes.

Start by slicing your zucchini and the onion (and shred your cheese if you didn’t get pre-shredded). I like to use a Mandoline Slicer, this way I get nice and even cuts. Once you’ve got that done, you’re going to take a 8″ casserole dish and start layering. You’re going to make 3 layers, so divide the zucchini, onion, and cheese into thirds. Start the layering with the zucchini, the onion, and the cheese. No need to be fancy with it, you’re just going to scoop it out and eat it when it’s done anyways!

Finish all three layers and then in a separate dish, whisk together the butter, whipping cream, garlic powder, and xanthan gum. Pour it over the veggies. Your prep is DONE!!

See, I don’t think you can get much easier than that! All that’s left to do is bake it!

Bake at 375 for about 40-45 minutes or until it’s nice and brown on the top, like this deliciousness ↓↓↓Zucchini au gratin done

Eating Healthy with Picky Eaters

I’m fairly certain I’m not the only one here that has family that includes picky eaters. Personally, I’ll try almost anything and I love fruits and vegetables, although I don’t always eat them as often as I should. My husband, on the other hand, is the pickiest eater of them all. His diet basically consists of meat, potatoes, pasta, and dessert – no fruit, no vegetables (other than the potatoes). My children don’t have a very expansive list of foods they will eat, but there are at least some fruits/veggies on them. My son definitely takes after my husband and I can’t count the amount of times I’ve heard ‘I don’t like that’ before they’ve even tried a bite. My daughter is more like me and will at least try something. Tonight was one of those nights she tried something new. Tonight I made Lemon Garlic Butter Steak with Zucchini Noodles (you can find the recipe I used here: https://www.eatwell101.com/garlic-butter-steak-and-zucchini-noodles-recipe). While mine wasn’t as pretty as the picture, it tasted amazing. When you get a thumbs up from your three year old daughter and she says ‘that’s really good’, it’s a good feeling knowing she is loving food that is good for her. It’s hard getting kids to eat and like healthy food, especially when you have a kiddo that likes to eat sweets and junk. I try not to keep too much in the house since I’m trying to lose weight, but that is what the husband eats, so it makes it a little more difficult.
Reducing the liquid while it was cooking
Ready to eat!
While the food was really good, I would make a couple modifications to the recipe. It seemed way too oily, so I would definitely cut back on that. I would even add a little more sriracha to the marinade. If you don’t like the heat, you can cut back on that and the red pepper flakes. You can definitely taste the lemon in this too. If you don’t like lemon, cut back on it. It could use more garlic though, the amount the recipe called for wasn’t enough for me. Another thing to note is that it definitely takes more than 15 minutes from start to finish, so the title is a little misleading. First off, you have the marinate the steak for 30 minutes and then you’re supposed to let it sit and get to room temp before cooking, plus you have to spiralize 4 zucchini. So unless you’re a super chef with the ability to stop time, it’s not going to happen in 15 minutes. Total I think it took more like an hour for me. Overall it was a really good recipe and I would make it again.
