Cheesy Spaghetti Squash Casserole with Bacon

Yesterday, as the evening light faded, I found myself craving something comforting yet not too heavy, a dish that would wrap me in warmth without weighing me down. That’s when the idea of a cheesy spaghetti squash casserole with bacon came to mind, a perfect blend of savory, creamy, and slightly sweet flavors.

Ingredients

• 1 medium spaghetti squash (about 3 lbs)
• 6 slices bacon, chopped (thick-cut preferred for more texture)
• 1 cup shredded cheddar cheese (sharp for more flavor)
• 1/2 cup heavy cream (or half-and-half for a lighter version)
• 2 tbsp unsalted butter (or olive oil for a dairy-free option)
• 1/2 tsp garlic powder (adjust to taste)
• Salt and pepper to taste (start with 1/4 tsp each)

Instructions

1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
2. Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil and season lightly with salt and pepper.
3. Place the squash halves cut-side down on the prepared baking sheet. Roast for 35-40 minutes, or until the flesh is tender and easily shreds into strands with a fork.
4. While the squash roasts, cook the chopped bacon in a skillet over medium heat until crispy, about 8-10 minutes. Transfer to a paper towel-lined plate to drain.
5. Once the squash is done, use a fork to scrape the flesh into strands into a large mixing bowl. Add the butter, heavy cream, garlic powder, half of the cheddar cheese, and the cooked bacon. Mix well to combine.
6. Transfer the mixture to a greased baking dish and sprinkle the remaining cheddar cheese on top. Bake at 375°F (190°C) for 15-20 minutes, or until the cheese is bubbly and slightly golden.
7. Let the casserole sit for 5 minutes before serving to allow the flavors to meld together beautifully.

Ingredients

– 1 medium spaghetti squash (about 4 cups when cooked, halved and seeds removed)

5. Remove the cream mixture from heat and stir in the Parmesan cheese until smooth. Tip: If the sauce seems too thick, a splash of milk can thin it to desired consistency.

7. Transfer the mixture to a greased 9×13 inch baking dish and sprinkle the top with mozzarella cheese.

By now, the edges are perfectly crisp, the center creamy and rich, with the nutty undertones of Parmesan weaving through each bite.

Spaghetti Squash Casserole with Caramelized Onions and Gruyere

Sometimes, the most comforting dishes come from the simplest ingredients, woven together with patience and care. This spaghetti squash casserole, with its layers of sweet caramelized onions and nutty Gruyere, is a testament to the beauty of slow cooking and the warmth it brings to the table.

Ingredients

• 1 medium spaghetti squash (about 3 lbs), halved and seeded
• 2 tbsp olive oil (or any neutral oil)
• 2 large yellow onions, thinly sliced
• 1 tsp salt (adjust to taste)
• 1/2 tsp black pepper (adjust to taste)
• 1 cup Gruyere cheese, grated (packed)
• 1/2 cup heavy cream
• 1/4 tsp nutmeg (freshly grated if possible)

Instructions

1. Preheat your oven to 375°F (190°C). Place the spaghetti squash halves cut-side down on a baking sheet lined with parchment paper. Roast for 40-45 minutes, or until the flesh is tender and easily shreds into strands with a fork.
2. While the squash roasts, heat olive oil in a large skillet over medium heat. Add the sliced onions, salt, and pepper. Cook, stirring occasionally, for 25-30 minutes, or until the onions are deeply golden and caramelized. Tip: Lower the heat if the onions start to burn.
3. Once the squash is done, use a fork to scrape the flesh into strands. In a large bowl, combine the squash strands, caramelized onions, heavy cream, and nutmeg. Mix gently to combine.
4. Transfer the mixture to a greased 9×13 inch baking dish. Sprinkle the grated Gruyere evenly over the top. Bake at 375°F (190°C) for 20-25 minutes, or until the cheese is bubbly and lightly golden. Tip: Let it rest for 5 minutes before serving for easier slicing.
5. For a crispy top, broil for the last 2-3 minutes of baking, watching closely to prevent burning.

Unassuming at first glance, this casserole reveals a delightful contrast of textures—creamy, tender squash against the crisp, cheesy crust. Serve it alongside a crisp green salad or as a hearty standalone dish on a chilly evening.

Spaghetti Squash Casserole with Roasted Red Peppers and Goat Cheese

Yesterday, as the evening light faded, I found myself craving something both comforting and slightly unexpected. This dish, with its tender strands of squash and creamy pockets of cheese, became my quiet kitchen companion.

Ingredients

• 1 medium spaghetti squash (about 3 lbs), halved and seeded
• 2 tbsp olive oil (or any neutral oil)
• 1 cup roasted red peppers, chopped (jarred is fine, but pat dry)
• 4 oz goat cheese, crumbled (room temperature blends easier)
• 1/2 tsp salt (adjust to taste)
• 1/4 tsp black pepper (freshly ground preferred)
• 1/4 cup fresh basil, thinly sliced (plus extra for garnish)

Instructions

1. Preheat your oven to 400°F. Line a baking sheet with parchment paper for easy cleanup.
2. Brush the cut sides of the spaghetti squash with olive oil and season with salt and pepper. Place cut-side down on the prepared baking sheet.
3. Roast for 35-40 minutes, or until the squash is tender when pierced with a fork. Let cool slightly to handle.
4. Use a fork to scrape the squash into strands, transferring to a large mixing bowl. Tip: Don’t overmix to keep the strands intact.
5. Gently fold in the roasted red peppers, goat cheese, and basil until just combined. Season with additional salt and pepper if needed.
6. Transfer the mixture to a greased 8×8 baking dish, spreading evenly. Bake at 375°F for 15-20 minutes, until the top is lightly golden.
7. Let the casserole sit for 5 minutes before serving. This rest time helps the flavors meld beautifully.

Warm from the oven, the casserole offers a delightful contrast of textures—silky squash, juicy peppers, and creamy cheese. Try serving it alongside a crisp green salad for a light yet satisfying meal.
