CHICKEN CASSEROLE

Who doesn’t love a good baked pasta casserole recipe? I’m a total 80’s kid, ya know, the generation of microwave dinners and casseroles. This French Onion Chicken Casserole is a far cry from the tuna casserole that I ate as a kid. Don’t get me wrong, tuna casserole is fine and all. We just ate it A LOT. I get it. It was cheap, easy and nutritious. But I ate tuna casserole so much as a kid that I have never considered making it as an adult. Aparently 25 years is too soon.

French Onion Chicken Casserole as a kid friendly meal may seem a little far fetched. But believe you me, this is a hit at my house! My daughter hates onions. She did pick out a few of the larger onions but ate the rest. All that ooey-gooey cheese helps to seal the deal.

This meal is all about the onions. I use Thrive® Algae Oil to get the onions perfectly golden and caramelized.

The health benefits of Thrive® Algae Oil are perfect for this nutritious family meal. It has the highest level of monounsaturated fat {the good fat} and the lowest level of saturated fat {the bad fat} with 75% less saturated fat than olive oil.

Thrive® Algae Oil has a light, neutral taste. It is great for caramelizing onions because it has a crazy high smoke point of 485°! And, Thrive® Algae Oil is sustainable. Their mission is to create an oil that is better for people and the planet.

I’ve used Thrive® Algae Oil to make Crispy Roasted Chickpeas, Cheesy Twice Baked Potatoes, Cheesy Zucchini Tots, Black Bean Burgers with Cilantro Lime Slaw, Sweet Chili Sauce and Butternut Squash Pasta Salad.

So this casserole. It is sort of like a baked mac and cheese with chicken and onions. You can prepare the onions ahead to save some time. Then you just need to cook the chicken, pasta and white cheese sauce. Mix it all up, top with cheese and bake.

Now you are ready to serve your family a unique casserole that is made with real ingredients. No boxes. No cans. No weird unpronounceable ingredients. Just a good old fashioned homemade casserole.

Some things from the 80’s should come back into style.
