This Lemon Chicken Spaghetti Squash recipe can be pre-baked and stored in the fridge for an easy meal prep dinner. When you’re ready for a delicious, gluten-free, low carb dinner, throw it all together and bake it up!

It’s our first post in September, and I couldn’t be happier! This summer was a BLAST, so jam packed with fun family activities, not to mention moving to our dream house.

But it was also a little exhausting at times, and extremely hot (for some reason the heat has been really bothering me this pregnancy!), and I am ready to move onto fall…and fall produce.

It’s about time that I share a spaghetti squash recipe with you, don’t you think?

And I am super excited about today’s recipe because it is oh-so-comforting, but guilt free, thank-you spaghetti squash! Let’s check out this lemon chicken spaghetti squash recipe, shall we?

I think I’m going to have to add spaghetti squash to my meal prep routine more often, because it. is. so. simple.

All you need to do is scoop your squash out and bake it for 45 or so minutes. That’s why we don’t normally eat it for dinner…because who has time to pre-bake a squash for 45 minutes on a weeknight? Not me.

But it is super easy to do this step ahead, cool, and store in the fridge. Your spaghetti squash will be good for up to 5 days afterwards, and you have just saved yourself 45 minutes in the kitchen!

While you’re baking your spaghetti squash, you might as well also bake up some chicken breasts. I normally bake mine at 425 but since this squash bakes at 350, I put the chicken in with it at 350 and increased the cook time to about 30 minutes (for 7 oz breasts).

Aaaand. While you’ve got the oven working for you, you can get to work on your lemon cream sauce!

Are you ready for this? Because there’s butter and heavy cream involved. But fear not, because one portion of this Lemon Chicken Spaghetti Squash recipe still only clocks in at 295 calories. Woo hoo!

For the lemon cream sauce, you’re going to cook some onions and garlic in butter. Prepare for your kitchen to smell like heaven.

Next: chicken stock, then some heavy cream and fresh lemon juice. Cook until heated through and completely combined, then store in a container in the fridge until you’re ready to cook everything up. This sauce will separate in the fridge, but pouring it back into a pan and heating through gently will bring it back together.

When you’re ready to bake up, shred the spaghetti squash into ‘noodle-y’ strands (let’s pretend ‘noodle-y’ is a word, OK?), scatter the chicken, pour the sauce over and mix it all up.

You’re going to bake it all right in the spaghetti squash!

I had originally intended these to be eaten right out of the spaghetti squash boats, but they were waaaay too much for one person to eat.

So you can get 2 portions per spaghetti squash, and if you still need a few carbs in your life (ahem…hungry pregnant lady speaking here!), 1 oz whole wheat spaghetti per person is a great supplement, while still keeping things light and even under 400 calories.

Tips for perfect lemon chicken spaghetti squash:

• I baked my squash in my favorite 9×13 pyrex baking dish, which perfectly fit two halves of a large spaghetti squash
• this recipe is also great with 2 cups of chopped kale mixed into the lemon cream sauce (the kale gets crispy while baking! But the kale also absorbs some of the sauce)
• the storage containers you see above are from this set of glass storage containers
