Salmon Hash Brown Casserole

This Salmon Hash Brown Casserole was born out of a desire to create an all-in-one meal using stuff I had already sitting in my pantry or freezer. And it worked out to be a super yummy, creamy textural casserole featuring salmon, harmonized with spinach and potatoes and just the right cheesy seasoning. I can't decide if it's more suited toward breakfast or dinner? Why label it? It's great for any meal of the day.

I love a good casserole! The word "casserole" might have negative connotations depending on your memories of them and what style you have been served. In the 1950's casseroles were popular, but then in the 1970's and 1980's "convenience" foods started to become a way of life. Have you ever eaten, made, or at least heard of "Tuna Casserole?" It was traditionally made with a huge can of tuna, a couple cans of "cream of..." condensed soups, and noodles and maybe some frozen mixed veggies like carrots and peas. I'm not always vegan, but I am always dairy-free and most of the time, gluten, or wheat-free. I wasn't even thinking about Tuna Casserole when I came up with my combination, but ironically, it is a similar, more sophisticated version, while still utilizing "stuff on hand" for convenience.

For Salmon Hash Brown Casserole, I started with a layer of spinach and tossed in a couple cans of Alaskan Salmon. I love salmon for its flavor, but also its high omega-3 fatty acids (the fat we need more of), and its high protein content. I keep a couple of cans of salmon in my pantry just for occasions such as this; when I want some easy-to-digest protein and healthy fat, but I don't want to run to the market to get fresh fish to cook. Canned is also far more budget-friendly than fresh Alaskan salmon. I covered the spinach-salmon layer with some whisked eggs to help it bind after baking.
For the main layer, I wanted to work with a bag of frozen potato hash browns. Potatoes are a great substitute for pasta, in that both provide complex starchy carbohydrates, but potatoes are a whole food, gluten-free, and low-FODMAP. To give the potatoes a creamy binder, I melted together some vegan cream cheese (I like Kite Hill), plus a little vegetable broth, and finally some vegan cheddar shreds. I added in some basic dried herbs, my favorite Aleppo pepper and a few hot pepper flakes. Spread this over the spinach layer, added more vegan cheese shreds and gluten-free panko bread crumbs to give the top a crunchy bite.

Potatoes, spinach, and salmon are all low-FODMAP, and also represent the "all-in-one" that I refer to in a good casserole. You've got your starchy carbs, a healthy protein source, and dark, leafy greens. This way, you don't need to think or prepare anything else for a well-rounded meal. I love serving this Salmon Hash Brown Casserole with northing more than a bottle of hot sauce.
Remaining ingredients in Salmon Hash Brown Casserole may include low levels of FODMAPs, and depend on the brands you choose. Be sure to read ingredients lists and know your body and what you can and cannot tolerate. Avoid garlic and onion in herbs and vegetable broth, you won't even miss those flavors in this flavorful casserole!
