Ingredients You’ll Need:

• 1 medium spaghetti squash (about 2–3 lbs)

• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1/2 cup sour cream
• 1 1/2 cups shredded sharp Cheddar cheese
• Salt and pepper, to taste
• Optional: chopped parsley for garnish

Step-by-Step Instructions:

Cook the Spaghetti Squash

• Preheat your oven to 400°F (200°C).
• Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds.
• Place both halves cut-side down on a baking sheet lined with parchment or foil.
• Roast in the oven for about 30–40 minutes, or until the flesh is tender and easily shredded with a fork.
• Let it cool slightly, then use a fork to scrape the inside into spaghetti-like strands.

Sauté the Aromatics

• While the squash cools, melt 2 tablespoons of butter in a large skillet over medium heat.
• Add the chopped onion and cook until it’s soft and translucent, about 5 minutes.
• Stir in the minced garlic and cook for another 30 seconds until fragrant.

Mix the Filling

• Add the shredded spaghetti squash to the skillet and stir everything together.
• Reduce the heat to low and mix in the sour cream, then season with salt and pepper to your taste.
• Stir in 1 cup of shredded Cheddar cheese, mixing until the cheese is melted and the mixture is creamy.

Bake It Up

• Preheat your oven’s broiler.
• Transfer the creamy squash mixture into a greased baking dish (8×8 or similar).
• Sprinkle the remaining 1/2 cup of Cheddar cheese evenly over the top.
• Broil for 2 to 4 minutes, or until the cheese is bubbly and golden brown. Keep a close eye on it so it doesn’t burn!

Garnish and Serve
