I love a good casserole. Especially one made with good for you ingredients and that doesn’t contain canned soup. Like this one.

This requires a few steps to put together the different components — roasting broccoli, making a cream sauce, cooking rice. But, the end result is delicious and fresh tasting.

Whenever I make anything with broccoli, I usually roast it first. Sometimes with an amazing spice blend. Sometimes with just lemon. Roasting changes the flavor in an amazing way, and I’ll never go back to bland, steamed broccoli again. It’s an extra step, sure. But it’s one that is mostly hands off, so you can do it while you’re doing other things, and you’ll be glad you did later.

Once the components are done, putting this together is easy. Just mix it all up, top with some cheese, and bake. Perfect for a side dish or if you’re like me, just dinner.
