Creamy Vegetable Casserole

This is going to sound ridiculous. I’ve never made a casserole. Not green bean, or tuna, or chicken, or cheeseburger casserole. In fact, it’s not even something that I can recall my mom making when I was growing up. And if she did, I probably wouldn’t have eaten it. I had that complex where I didn’t like my food touching or mixing with other food.

I thank God I overcame that crippling disorder because now I can appreciate things like this incredible casserole. Brussels sprouts meet sweet potatoes meet cauliflower in perfect harmony.

Now that I’ve made one, I really like the simplicity of casserole. Life is already too busy as it is. Commute, work, commute, make dinner, prepare lunch, do it all over again the next day. Weekends are filled with making blog recipes and working on side projects. Heck, I’m currently writing this post from the subway platform at Nevins Street in Brooklyn.

The best thing about this casserole is that we made it on Sunday and we had dinner for the next two nights. Pop it in the oven and take it out when it’s hot. Meanwhile, I have more time to enjoy my husband’s company. That’s what I call winning.

There is never enough time for things like this. At the end of every day, I find myself longing for more. More time with Clark. More popcorn on the couch. More deep conversations. More exploring in Brooklyn. More soup at our makeshift dining table. More time with friends. More Netflix reruns of That 70’s show. More minutes for Skyping family. More time for the blog. I like meals like this casserole because it gives me more time for any of the above.

Now, let’s talk about the flavor in this thing. Forget about green beans; there’s a new casserole in town. There may be a little more effort involved, but it’s worth it. This dish combines the absolute best ingredients into flavorful bite after bite. Each veggie adds to the taste and the creamy sauce brings it all together. If you’ve never made spaghetti squash before, have no fear. Just visit this post for an easy walk-through of how it’s done.

My favorite secret weapon – rosemary – is the perfect complement to the flavors that are already going on. You won’t believe how good your house smells while it’s in the oven.

    Please clarify the spaghetti squash. You bake and scrape it then roast it again? Do you mix it in with everything else at the end or do you serve other veggies on top of it? I don’t see where you used it. Looks delish! Thank you!

    Hi there. Is it really only 1/2 cup of sweet potato and the other items? It looks like more in the photo. Thanks!

    • thefitchen says

      Yep! Just 1/2 cup. There was a bigger quantity in the photo, but we just saved that for leftovers! You could probably add more if you feel like it. :)

    This is the first time I have been to your blog, and I am excited to follow you. After making this for dinner tonight, I will be visiting here more often. It was delicious! Thanks for the great recipe.

    Hated cauliflower and was grossed out by brussel sprouts before trying this recipe last night. It was FABULOUS! We have told a million people about it already, haha, this was insanely good. We used feta because we didn’t have goat cheese, that was good too! Thank you for opening my good world to two previously hated veggies!! =)

    • thefitchen says

      Well, score!!! I feel better knowing that we’ve succeeded in helping you like two new, awesome veggies! Brussels sprouts are close to the top on my list. <3 So glad you enjoyed!

    This recipe sounds very yummy and I’ll definitely be trying it soon. Though any suggestions for replacing the sweet potato in the recipe? My daughter is allergic to sweet potatoes. I’m sure regular potatoes would work but not provide quite the same flavor profile.

    • thefitchen says

      I would try substituting with a creamier type of potato with some flavor – not just a standard Idaho. A Yukon gold would be a perfect substitute! Let me know how you, and your daughter, like it!

    This looks delicious! How important is the cheese? I’m on day 21 of AIP elimination and looking for thanksgiving recipes. I’d have to omit the dairy and black pepper, but I think it might work. Thoughts?

    • thefitchen says

      Absolutely! You could just leave out the goat cheese, without a problem. Of course, the flavor won’t be quite the same, but it will still be delicious. :)
