Instructions

Cook rice according to package instructions. Set rice aside to cool while you’re prepping the rest of the recipe.
Preheat the oven to 400 degrees F.
In a large mixing bowl, whisk together the almond milk, eggs, mayonnaise (or butter), sea salt, stone ground mustard, and 2 cups of the mozzarella cheese to a mixing bowl (you’ll use the remaining 1 cup of cheese for the topping). Whisk this mixture together until it is well-combined. Add the drained tuna and rice and mix well to combine.
Transfer to a mixing bowl to a casserole dish (I use an 9” x 9” square casserole dish).
Top the casserole with the remaining cheese (add more if desired!) and place on the center rack of the preheated oven. Bake for 20-30 minutes, or until the cheese is melted and begins turning golden-brown and the center of the casserole reaches 160 degrees Fahrenheit. To check the internal temperature of the casserole, insert a meat thermometer into the center and wait until the numbers stop moving. Allow casserole to cool 5 to 10 minutes before serving.

Notes

*or cow's milk, oat milk, full-fat canned coconut milk, rice milk, or cashew milk
**You can also use melted butter, ghee, or avocado oil in place of the avocado oil mayo.
***Use jack cheese, Gruyere, Gouda or melting cheese of choice. You can keep the recipe entirely dairy-free by using a vegan "cheese"
If you use leftover cooked rice that is cold, the casserole may require closer to 30-35 minutes to bake in the oven due to its lower temperature going into the oven.
