Avocado & Potato Gratin with Salmon: Superfood in Casserole Form

If you’re like me, you’ve always associated avocados with cold dishes. On bread, in salads, or even as a dip, avocado simply makes everything better. But have you ever eaten avocado warm? I hadn’t, until I discovered this casserole. The innovation, like so many, was born from necessity. I found myself, once again, with too many avocados on my hand! They had ripened at the same time and I was long running out of salad ideas. A big fan of salmon and avocado, I thought, well what would happen if we bring this into a casserole? Thus came the potato and avocado gratin with salmon.

And it really packs a punch. Not only does it taste absolutely amazing. Avocado not only provides a particularly velvety consistency, but also brings an extra portion of healthy, unsaturated fatty acids into play. The same also goes for the salmon, because it is rich in omega-3 fatty acids which promote healthy blood pressure levels. Omega-3s are especially important as they can’t actually be produced by the body itself!

The good news is that our potato and avocado gratin with salmon will make sure you’re well taken care of. And not only that, but it will also leave you full and satisfied, If that wasn’t good enough, it’s also easy to make: Layer potato slices in a baking dish, top with salmon and avocado cubes, and pour your homemade cream sauce on top. The whole thing goes into the oven at 350°F for about 45 minutes, until the surface is golden brown and the potatoes are soft. The smell alone will make your mouth water. And just wait until you try the first bite. Heavenly!
