With just four ingredients, this make-ahead Spaghetti Squash Alfredo Bake is not only easy to make… it’s absolutely delicious! Add in cooked chicken or shrimp to add some protein to this vegetarian dish.
I’ve been so into my zoodler lately, that I’ve neglected the easiest vegetable noodle of all – spaghetti squash! It’s probably been a year since I last roasted a spaghetti squash; I forgot how much fun it is. There’s something magical about cutting open a cooked spaghetti squash to find ribbons of veggie noodles. Nature is just so cool. And when I saw RAGÚ products were buy-one-get-one-free at Publix, I knew what I had to do…
I feel way less-guilty when I re-create favorite pasta dishes with veggies. Take a carb-heavy recipe like fettuccine Alfredo. When made with spaghetti squash and mushrooms, it can be a recipe in my weekly meal plan. Even better? I can make it earlier in the day and pop it into the oven 45 minutes before dinner. Oh, and did I mention you need just four ingredients? Yep.
With RAGÚ® Cheese Creations Classic Alfredo Pasta Sauce, a spaghetti squash, mushrooms and mozzarella, dinner is served. RAGÚ Classic Alfredo is a thick, creamy Alfredo sauce that is packed with Parmesan and Romano cheeses. It is made with real cheese and fresh cream so it is bursting with cheese flavor.
If your family just can’t have dinner without meat, add in some cooked shrimp or chicken for an extra dose of protein.
Spaghetti Squash Alfredo Bake
Preheat an oven to 375 degrees Fahrenheit. Pierce the spaghetti squash in a few places with a knife. Place in a baking dish and cook for about 1 hour, or until tender when pierced with a knife. Allow it to cool enough so it’s easy to handle.
Meanwhile, bring a large skillet to medium-high heat and coat with cooking spray. Add the mushrooms in an EVEN layer. Be sure to use a large enough skillet so you don’t crowd the mushrooms. This allows them to brown instead of steam, which makes them taste sooo much better!
After placing the mushrooms in the skillet, let them cook for 3-4 minutes before stirring. Cook until all liquid has evaporated and they are golden brown. Season with salt and pepper.
Cut the spaghetti squash in half length-wise and scoop out the seeds. Using a fork, scrape out the spaghetti “noodles” into a large bowl. Leave just a little bit of flesh to each shell so that it easily keeps it shape. Place the shells back in the baking dish.
Add the mushrooms to the bowl and fold in 2 to 2 1/2 cups of sauce. Stir to coat.
Divide the mixture amongst the two spaghetti squash shells. Top with an additional drizzle of sauce and sprinkle with cheese.
Return the squash back to the oven and cook until mixture is bubbly and the cheese is golden. Allow it to cool five minutes before serving. Garnish with parsley, if desired.

Made this with my own Alfredo….well, beschemel. (is off the shelf Alfredo a single ingredient? Is it even ‘Alfredo? spoiler: no! it’s a beschemel, still rather delicious!) And indeed, this is a terrific recipe.
When chef Alfredo made his eponymous sauce, it was made at tableside of only butter, grated parmesan, and pepper, which he tossed with the fettucine.
Thanks for all of these great recipes! I can’t wait to try the lime chicken tacos.
My pleasure! Let me know how they turn out!
This so AMAZING! This is a dish that I would totally make for myself and probably keep for myself. My grandmother used to make something similar when I was a little girl.
Wow! Glad you liked it!
