Brown the ground beef with the minced onions, seasoned salt, and black pepper. Drain the excess grease. Stir in the pasta sauce and set aside.
Bring the heavy cream, minced garlic, and black pepper to a simmer over medium heat. Add the cream cheese and butter. Stir in the shredded parmesan, one bit at a time, until smooth. Remove from heat and set aside.
Spread half of the spaghetti squash in a greased 9×9 pan.
Pour the alfredo sauce over the spaghetti squash.
Top with the remaining spaghetti squash and spread the meat sauce over it.
Top with the shredded mozzarella cheese.
Bake at 350°F degrees for 35-45 minutes until the mozzarella on top is golden and the sauce is bubbling.
Million Dollar Spaghetti Squash Recipe Tips:
- Want to go meatless or save time? Skip the ground beef and just use pasta sauce.
- Don’t want to use ground beef? Substitute with ground chicken.
- Not in the mood to make homemade alfredo sauce? Use store bought. The better the quality (get the refrigerated sauce instead of the jarred) the better your million dollar spaghetti squash will turn out.
- Want to lower the fat or calories? Choose lean ground beef and low-fat mozzarella cheese. For the alfredo sauce, purchase light alfredo sauce or make homemade using fat-free half-n-half, low-fat cream cheese, skip the butter (use more half-n-half if it needs to be thinned). BUT keep in mind that all of the substitutions will change the flavor and texture of the million dollar spaghetti squash.
- Wondering how to make spaghetti squash? Here is my microwave spaghetti squash recipe and here is my recipe for how to make spaghetti squash in an instant pot.
- How much spaghetti squash do you get from one cooked spaghetti squash? It depends on the size of the spaghetti squash. I’ve found that I typically get about 2 1/2 cups from the ones I buy.
- Don’t like spaghetti squash? Use spaghetti noodles instead.
- Need to feed more than 6 people? Double the recipe and make it in a 9×13 casserole dish.
- Have leftovers? Cut the million dollar spaghetti squash into servings, put them in small individual containers, and place in the freezer for a quick meal for one.

HOLY MOLY! THIS IS AMAZING. I made it for xmas to keep on track with my low carb lifestyle. wow this is out of this world. I doubled everything except for the alfredo. I kept it at the regular amounts to save on calofies and to not make it too creamy. and it was amazing. It reminds me of a butternut squash lasagna from Giada delaurentis. Im going to blend basil into the sauce the next time and I bet it’ll taste just like it. so delish!

We had no leftovers! Maybe next time I will double the recipe.
Erin says
This is a great recipe. I used the vegetarian version and had this while my picky family ate regular lasagna. I did not feel left out! Loved the Alfredo sauce. This is a great recipe!
Tonia says
That is fabulous! I’m happy to hear that you enjoyed it!
Kelsie says
This might be a stupid question, but does the spaghetti squash need to be cooked before putting it into the 9×9 dish?
Tonia says
Hi Kelsie!
Yes, it does have to be cooked first. Spaghetti squash is hard and softens as it is cooked allowing you to get the “spaghetti” strands. You can find my instructions for how to cook spaghetti squash in the microwave here: https://www.thegunnysack.com/cook-spaghetti-squash-microwave/
Happy cooking!

We loved this recipe!!! It’s going to be one of my go-to recipes from now on! The squash was so easy cooking in microwave.

Oh. My Gosh.
This is one of the top 3 favorite low carb recipes I have ever made. I added 1/2 lb. hot sausage and mushrooms to the meat sauce and used one diced onion in place of the minced onion and holy WOW this was just heavenly. Even my non-low carb family members scarfed it down!
I already can’t wait to eat the leftovers for lunch today. THANK YOU Tonia for this now staple in my weekly dinner rotation!!
