Healthy Keto Tuna Casserole (easy & Creamy!)

I love them, but they just don’t love me. One of my favorite things before going on a keto diet was a good cheesy pasta or rice casserole. This Cheesy Chicken and Rice was my particular indulgence in my pre-keto days.

I wanted to recreate some of those good old classic flavors from dishes most of us grew up knowing and loving. So this cheesy tuna casserole is my first in a long list of keto comfort foods!

This dish is packed with zucchini noodles (I have a trick to prevent them from being soggy and watery), a creamy cheese sauce, and chunks of tuna.

How To Make And Cook Zucchini Noodles

The key to this recipe is prepping your zucchini noodles. Zucchini is full of liquid, so you must pre-bake your zoodles to remove the moisture, otherwise your creamy cheesy sauce will turn out very watery.

This dish is only 3.4 net carbs per serving and it is so satisfying! The casserole serves 6, so you can meal prep the recipe if desired.

This creamy baked tuna casserole pairs nicely with almost any vegetable or salad. Here are some side dish ideas to get you started:

Low Carb Zucchini Ground Beef Casserole

Bake zoodles at 10 minute intervals. Remove and stir every 10 minutes, continue baking at 10 minute intervals until the moisture has evaporated.

**Depending on the size and moisture level of the zucchini this may take between 10-20 minutes. Remove when moisture as evaporated and they have shrunk in size, but before they are brown or crispy.**

While zoodles are pre-baking heat a medium size skillet over medium heat melt the butter, add the garlic, almond milk, heavy cream, cream cheese and 1 cup of the cheddar cheese. Whisk mixture until it is smooth and cheese has melted, stir in drained tuna. Remove from heat.

Keto Tuna Zoodle Casserole Recipe

If you have ever added zucchini to a baked dish you know that it releases a lot of moisture as it cooks. There are many ways to try to combat this such as sprinkling the sliced zucchini with salt and allowing it to sit out and naturally release moisture over time. However, I find that this method takes a lot of time and only removes some moisture, resulting in an ultimately soggy dish.

My much easier method is to pre-bake the zucchini noodles while you prepare the rest of the dish. Allowing the noodles to cook all by themselves releases tons of moisture and ensures your dish is perfectly creamy, not soggy.

I love a good casserole. There is something totally comforting about it. I’ve come up with keto friendly versions for lots of my classic favorites. This Cheesy Tuna Zoodle Casserole has everything you love about traditional tuna casserole, without the carbs.

One of the most popular non-keto recipes on this site is my One Pan Taco Mac. I have always loved how easy and comforting a good pasta dish is. This recipe is a spin on taco mac, but instead of using regular pasta noodles I made zucchini noodles (aka zoodles).

Zoodles are zucchini spiraled into noodle form. Sadly, noodles are a no go on a keto diet. I have found that when properly prepared zoodles really are the perfect low carb replacement!

This low carb taco casserole has three main components: the zucchini noodles, the cheese sauce, and the taco meat. Here’s what you’ll need to make the healthy taco casserole:

French Onion Zoodle Bake

Almond milk is used to keep the carb count low. If you aren’t concerned with carbs you can use any variety of milk you prefer.

Like most people, I have tried zucchini lasagna or other dishes with zucchini in place of pasta and am always disappointed by how much moisture there is.I have tried salting them and letting them set out, grilling, etc but nothing seems to work. The trick to solving it seems to be pre-baking the noodles.

The only tricky part is that there is no hard and fast rule on how long to pre-bake them. Depending on the size of the zucchini or level of moisture, it can take a little longer. For me, it has been anywhere for 10-20 minutes.
