Can you believe that we are almost officially in September? I walked into a Starbucks the other day and there was a sign that had a Pumpkin Spice Latte countdown on it… guys it read 6 days!


How are we already starting the “all things Pumpkin season!” This week in Texas, we’ve literally had heat advisory in the afternoon. By 3pm the heat index is 113 degrees F. I can’t even think of Pumpkins right now! It still feels like we are in the dog days of summer.

However, even though down south we are blazing hot. The reality is school has started and we are less than a month from the 1st day of Fall. Fall to me means school routines are in full swing, the holidays are just around the corner, things are nice and cozy and comfort food is at every corner.

What do you think of when I say comfort food?

Do you think mac and cheese? Or hamburgers? Or what about a big steak salad? Or a moist slice of double chocolate cake?

I’d like to say all of the above.

Guys. I like food. What can I say. It’s all comfort to me, I don’t discriminate.

But the epitome of “comfort” to me is all things cheesy. I grew up on cheese. After all, remember I AM a Wisconsin Cheesehead born and raised. It’s in my blood. So any chance I get to cover something with cheesy goodness I’m taking it.

And this Chicken Alfredo Stuffed Spaghetti Squash screams comfort to me.

Normally Alfredo sauce is made with parmesan cheese but today we are changing things up and adding Cabot White Sharp Cheddar Cheese.

Cabot is one of my favorite cheese brands. I’ve noticed that whenever I put together a cheese board I usually have one or two of their products because I know that it will be quality, have deep flavor and is always creamy! Hands down one of my go to cheeses is their Extra Sharp Cheddar Cheese! Y’all I could eat a block of it all by myself… unfortunately I have to fight my husband because he likes cheese too! Especially this kind because All Cabot Cheddars are naturally lactose-free… and my man is all about the lactose free! hehe

Cabot is a co-operative owned by 1,000 family farms throughout New England & New York. The awesome thing is 100% of the profits go back to the farmers. Woot Woot! What I love about Cabot is, they are deeply committed to making the finest cheese and dairy products on earth. And you can taste it in their product! They’re dairy farmers and cheesemakers, they feel lucky that they get to do things their way. The right way.

Even though I’ve used their cheese blocks plenty of times on my cheese boards I’ve never actually used their shredded cheese. Well, I’m changing that today in this Chicken Alfredo Stuffed Spaghetti Squash. Now, let’s go back to the whole Alfredo situation. Like I said, we are using cheddar instead of parmesan. The sharp cheddar gives the sauce a nice cheesy tang that you won’t get from parmesan. The cheese sauce combined with the sweetness from the spaghetti squash makes one dynamite bite.

Not only is this recipe easy to make (cuz ya know.. that’s what I like to do) but it’s so flavorful. Just a warning. You’re gonna be addicted to the sauce! For realz. It’s delicious cheesy goodness!

Bon Appetit!

  1. This recipe was just delicious. Super rich and creamy. I followed most of it to tee except I doubled the recipe and did 1/2 half & half and 1/2 whipping cream. Also, instead of rotisserie chicken, I cut 3 large chicken breasts into pieces. Then, heated 3 T of butter in a skillet, added my chicken, about a teaspoon of Oregano, a teaspoon of sage, a teaspoon of Italian seasoning and a teaspoon and a half of garlic salt. I simmered that on medium heat until cooked through.
