Cheesy Tuna and Cauliflower Rice Casserole

I wanted something comfort-food like that would also be Lent allowed.

Most people I know have cauliflower in their freezer and tuna in their pantries, so this could really be an easy, pantry meal that takes about 10 minutes from start to finish.

  • I normally would put the notes at the bottom, but because it’s not always obvious:
  • Dairy: I use mostly regular dairy but most of my recipes would work with unsweetened almond milk, coconut milk, cashew milk; cashew cheese, vegan options, etc – use what works for you. That being said: some alternatives might not thicken up as well, so use some xanthan gum or arrowroot if needed.
  • I include my cheese preference in the recipe, but if you don’t like Parmesan or Cheddar, or whatever, use what YOU like.

Cheesy Tuna and Cauliflower Rice Casserole 

  • This recipe makes 2-3 serving, the info at the bottom is for the entire recipe -divide into the number of servings you get.
    • 12 ounce, Frozen Cauliflower thawed and riced
    • 2 cans Wild Caught Chunk Light Tuna in Water, drained (2 of the 4-5oz cans, or 1 12oz can)
    • 0.50 cup chopped, Celery, raw
    • 2 tbsp chopped, Shallots, raw (or 2 green onions, sliced)
    • 4 Tbsp.  Heavy Whipping Cream
    • 2 oz sharp cheddar cheese, grated or chopped into small pieces (1oz cheddar and 1oz gouda work well, too)
    • 2 tbsp avocado oil

Saute the celery and shallots in avocado oil until they start to soften. Add the cauliflower and stir until it starts to lightly turn color, then add the tuna and seasonings of your choice*. Stir until tuna is heated through, then add the cream, stir and add in the cheese. Stir well and remove from heat to allow the cheese to finish melting.

*I keep the seasoning simple with just a little salt and pepper, but dill, tarragon, whatever you like -go for it 🙂
