Baked Spaghetti

Today was a snow day for my two oldest so all the plans I had for tackling my to-do list went out the window. NYC got lots of snow plus 40 mph winds, so no school! Yes, I love having my kids home because that means I get to spend more time with them but man oh man is it frustrating when you’re starting to get momentum and excitement for the new year just to be psychologically tripped at the starting line before you get started!

Regardless, I was able to spend less time at the computer, but more time in the kitchen today which means more recipes!! I documented a lot of this recipe on my instagram stories this afternoon and a lot of you seemed to be super excited about it, so I’m quickly posting it while I have a minute alone while my kiddos are in bed (but not asleep so hold your breath!)

Baked Spaghetti, or sometimes referred to as Million Dollar Spaghetti, is a huge spaghetti casserole that is covered with sauce, cheese and butter (!!!) and baked until hot and bubbly. It is pretty phenomenal, but since we’re all looking to be a bit healthier in the new year, I thought I’d create a lighter version with more protein and much less fat. Carbs, yes, but much more figure-friendly than the original.

I use 95% ground beef, onion, Rao’s jarred marinara, lots of mushrooms and garlic to create a lower fat tomato-based meat sauce. The pasta I used was a spaghetti high in protein and fiber. And of course, I topped the whole thing with a light bechamel sauce and a sprinkling of parmesan cheese. Bake this off until hot and serve as you like!

Of course if you have a better tomato sauce you’d prefer than this one I used, feel free to use that instead. This or this are great options. Also, just using straight up jarred marinara with a few veggies would work too. You do you, buttercup 🙂

    It’s awesome how quickly you put this recipe up! I was drooling over your Instagram stories lol. Carbs might be evil, but let’s be real, I still love them!!! I also love seeing a recipe that incorporates healthy ingredients but is realistic in what I really WANT to eat. It’s honestly refreshing not to see a salad recipe in January 😳😂 Thanks so much for the recipe! And stay safe and warm during that blizzard! Kind of wish Kentucky was getting some lol.

      Yes you could

      If you need to make it dairy free you could use almond milk in place of milk and Daiya or Follow Your Heart “cheese” as well. This is how I made it since I have a dairy intolerance. It was delicious. I still was able to do the butter, lucky for me butter seems to be OK.

    This was really good! My husband who really doesn’t like spaghetti, loved this! It made enough to feed an army, which was great because we had leftovers! The protein pasta was surprisingly good, too!

    We recently had a death in the family, so comfort food is of paramount importance. This looks as though it would fit the bill quite nicely.
