Spaghetti squash with mussels is easy, budget-friendly, and perfect for fall

This spaghetti squash recipe will be the star of your meal

When fall foods come to mind, one doesn’t often think of shellfish, but September is when so much of the best seafood comes into season. Mussels are one such treat. A less popular and highly underrated member of the mollusk family, mussels often take a backseat to their more fashionable cousins, like clams and oysters. This is a real shame, because mussels are absolutely delicious, very affordable, easy-to-cook, delectable treats, and you should start eating them asap. They’re also a wonderful source of protein, vitamin B12, and omega-3 fatty acids.

Simply steamed in a bath of white wine, broiled, or grilled, these little delicacies are sure to win you over. Our favorite preparation, though, is served over a bed of another fabulous autumn ingredient — spaghetti squash. When paired together, these two underdogs of the fall food list are a thing of perfection. Spaghetti squash is a delightful alternative to other fall squashes as it not only has a beautifully mild sweetness, but a wonderful, fun spaghetti-like shape.

A few notes on selecting and storing mussels: Always be sure your mussels are fresh (alive), by checking that each one is tightly closed when purchased. The shells should have a nice shine to them, and their scent should be pleasantly salty, like the sea. There should be no trace of a “fishy” smell. You can store your mussels in a bowl in the refrigerator, covered with a damp cloth for up to about a day before cooking.

Spaghetti squash with mussels recipe

Lindsay Parrill/The Manual

This recipe will serve about four…technically. In our experience, though, this dish is so good that the “serving size” isn’t always enough. You may want to double the recipe. Be sure to serve with lots of warm, buttery, crusty bread because the sauce is too good to lose even a drop.


  • 2 large spaghetti squash
  • 1 pound of fresh mussels
  • 6 tablespoons olive oil, divided
  • 1 tablespoon Old Bay seasoning
  • 1 teaspoon garlic salt
  • salt and pepper to taste
  • 1/2 yellow onion, minced
  • 2-3 garlic cloves, minced
  • 3/4 cup dry white wine
  • 1/2 cup chicken stock
  • 1/2 cup heavy cream
  • 1/4 cup lemon juice
  • 1/4 cup parsley, roughly chopped


  1. Preheat the oven to 350F.
  2. Rinse mussels in cold water and set aside.
  3. Cut both squashes in half vertically, and remove pulp and seeds with a spoon.
  4.  Place all four squash halves cut side up on a baking sheet, drizzle with 4 tablespoons olive oil, and season with salt, pepper, garlic salt, and Old Bay.
  5. Bake for 1 hour or until squash is fork tender.
  6. When squash is nearly done, sauté onion in 2 tablespoons olive oil until soft.
  7. Add garlic and continue to cook until onion and garlic are slightly caramelized.
  8. Add chicken stock, wine, lemon juice, and cream, and stir to combine.
  9. Immediately add mussels and cover the pot with a lid.
  10. Simmer, covered, 5-7 minutes until all of the mussels have opened. Discard any that haven’t.
  11. While mussels are cooking, scrape the inside of the squash with a fork, mix, and place onto a serving platter. The squash will resemble spaghetti.
  12. Pour mussel mixture over the squash, garnish with parsley, and serve.

Not only is this dish incredibly delicious, but it’s almost embarrassingly easy to make, very budget-friendly, and impressive enough for guests. So while we all adore a buttery pumpkin soup or warm bowl of chili on a crisp fall evening, why not branch out and try something a little bit different? We’re sure this will be a repeat dish in your fall recipe repertoire.

The secret to making your tequila drinks fall-friendly is Aperol
Need to transition your tequila drinks into the fall season? Look no further than Aperol
Aperol spritz

As the warmth of summer has faded into the cooler weather, as it always does, many people think the changing of the seasons means fewer frozen margaritas. And while that might be true, just because it's not frozen drink weather, it doesn't mean you have to give up tequila. The agave spirit can transition into fall seamlessly with the bittersweet touch of Aperol, among a few other things.

First, a bit of history. Aperol is more than a century old, a famously red-orange bitter apéritif born in northern Italy. It's a lighter cousin of Campari, both in terms of hue and alcoholic heat. Mostly, it's incorporated into a spritz. Yet, Aperol works wonders when it's combined with tequila, especially as you look to add a little more depth and weight to your drinks as autumn arrives.

Dill pickle pimento cheese dip

Even if golf isn't really your thing, you must know that, apart from the sport itself, the Masters is really all about one thing for those who attend — the Pimento Cheese sandwiches. Alright, that's probably an exaggeration, given that the Masters is a pretty big deal when it comes to golf. But for those of us who, honestly, attend just about any event solely for the food, it all comes down to the snacks.
The famous Masters' pimento cheese sandwiches started back in the late 40s when husband and wife Hodges and Ola Herndon whipped up a big batch and sold them to hungry golfers and fans at the famous tournament. At the time, a quarter was the going rate for this delicious snack, which has now, thanks to adoring fans, become a staple of Masters' tradition.

Now sold for a mere $1.50 a piece, the pimento cheese sandwich legacy lives on, being sold at Augusta National's concession stands throughout the tournament. They're made fresh every day and come wrapped in grassy green plastic bags for easy eating on the go.
If you're one of those golf fans who's mourning the end of the Masters and just can't wait a whole year for the return of its festivities, we've got some good news for you. Wye Hill Kitchen & Brewing in Raleigh, N.C. has created their own personal twist on this Masters' classic that you can make at home. Wye Hill has shared their incredible recipe exclusively with The Manual, and we can't get enough of this dip. It marries creamy housemade pimento cheese and tangy dill pickle relish for the ultimate shareable snack.
So whether it's the golf tournament, baseball game, or Dancing with the Stars finale, this incredibly delectable snack will have every single person reaching for more.
