Ingredients You’ll Need

• 1 small spaghetti squash, cut in half lengthwise, seeds removed: The star ingredient that creates a healthy, pasta-like vegetable base.
• 4 tsp olive oil, divided: Used to roast the squash for a caramelized finish and to sauté the kale gently.
• Sea salt and freshly cracked pepper, to taste: Essential for seasoning and bringing all ingredients into balance.
• 1½ tbsp butter: For browning, which adds a deep, nutty flavor profile that transforms the dish.
• 2 cloves of garlic, sliced thinly: Provides aromatic warmth and subtle bite.
• 2½ cups lacinato kale, stems removed & chopped: Adds hearty texture and earthy green goodness.
• 2 sprigs fresh thyme, leaves only: Brings a fragrant, herbal note that complements both kale and butter beautifully.
• Pinch of crushed red pepper flakes, to taste: A gentle heat boost to awaken your taste buds.
• 2 tbsp toasted pine nuts: Adds crunch and a buttery nuttiness, elevating the texture.
• ⅓ cup Fontina cheese, shredded: Melts into creamy indulgence that ties the flavors together wonderfully.
• Fresh parsley, chopped, for garnish: Gives a fresh, vibrant finish to every bite.
• Lemon wedges, for serving: A squeeze of bright acidity to balance the richness.

How to Make Brown Butter Kale and Fontina Spaghetti Squash Recipe

Step 1: Prepare and Roast the Spaghetti Squash

Begin by preheating your oven to 400°F (200°C). Lightly brush the cut sides of the spaghetti squash halves with 2 teaspoons of olive oil and sprinkle with sea salt and cracked pepper. Place them cut-side down on a baking sheet lined with parchment paper. Roast for about 35-40 minutes until the flesh is tender and can be easily shredded with a fork into spaghetti-like strands. This roasting step is crucial as it softens the squash and brings out its natural sweetness, forming the perfect base for the dish.

Step 2: Brown the Butter and Infuse with Garlic

While the squash roasts, melt the butter in a large skillet over medium heat. Keep an eye as the butter begins to foam and then starts to turn golden brown with a nutty aroma. Just as it browns, add the thinly sliced garlic so it can gently crisp without burning. This brown butter garlic combo is the flavorful backbone of the Brown Butter Kale and Fontina Spaghetti Squash Recipe, adding depth and warmth that infuse everything that follows.

Step 3: Sauté the Kale and Seasonings

Next, add the remaining 2 teaspoons of olive oil to the skillet along with the chopped kale, fresh thyme leaves, and crushed red pepper flakes. Toss and cook until the kale softens but still maintains a slight chew, about 4-5 minutes. This step gives the dish its bright green color and earthy vegetal note, while the thyme and red pepper flakes elevate the overall complexity.

Step 4: Combine Spaghetti Squash with the Kale Mixture

Once the squash is roasted and cooled enough to handle, use a fork to scrape out the strands directly into the skillet with the kale and brown butter. Toss everything together, allowing the squash to soak up the buttery, garlicky flavors. At this point, sprinkle in the toasted pine nuts and shredded Fontina cheese, stirring just enough for the cheese to melt into luscious pockets of creamy delight amidst the strands. The combination of textures and flavors here is what makes this Brown Butter Kale and Fontina Spaghetti Squash Recipe so utterly satisfying.

How to Serve Brown Butter Kale and Fontina Spaghetti Squash Recipe

Garnishes

Freshly chopped parsley is the perfect finishing touch, adding vibrant color and herbaceous brightness. Don’t forget a squeeze of lemon juice right before serving — the citrus cuttings through the richness and wakes up your palate beautifully. These small details take the dish from hearty and comforting to fresh and lively on the plate.

Side Dishes

This dish shines wonderfully as a stand-alone vegetarian main, but if you want to round out a meal, consider pairing it with a simple green salad dressed in lemon vinaigrette or some crusty artisan bread to soak up every last bit of brown butter sauce. Grilled chicken or roasted salmon would also complement it nicely if you’d like to add protein.

Creative Ways to Present

For an elegant twist, serve the Brown Butter Kale and Fontina Spaghetti Squash Recipe inside the hollowed-out baked spaghetti squash shells themselves. This presentation adds flair and keeps dishes minimal. Alternatively, try layering the squash mixture in small ramekins topped with extra Fontina and broiling briefly for a bubbly, golden crust.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually marry and deepen overnight, making it a great recipe to enjoy as a quick lunch or dinner the next day.

Freezing

While the texture of the kale might soften a bit upon freezing, you can freeze the Brown Butter Kale and Fontina Spaghetti Squash Recipe in portioned containers for 1-2 months. Thaw in the fridge overnight before reheating.

Reheating

Reheat gently in a skillet over medium-low heat to preserve texture, adding a small splash of olive oil or water if it feels dry. Avoid microwave reheating if possible, as it can make the kale mushy and the squash less appetizing.

FAQs

Can I use a different type of cheese instead of Fontina?

Absolutely! Fontina melts beautifully and has a mild, nutty flavor, but you can substitute with Gruyere, mozzarella, or even a young white cheddar depending on your preference. Just keep in mind the melting quality to maintain that gooey texture.

Is it necessary to use brown butter in this recipe?

While regular melted butter will work, brown butter adds a rich, roasted nuttiness that truly elevates this dish. It’s worth the extra attention during cooking for the flavor boost.

Can I prepare this dish vegan?

Yes! Simply swap the butter for vegan butter or olive oil and replace Fontina cheese with a plant-based cheese alternative that melts well or nutritional yeast for a cheesy flavor. The rest of the ingredients are naturally vegan.

How do I select the right spaghetti squash?

Choose a squash that feels heavy for its size with a firm, unblemished skin. Smaller to medium-sized spaghetti squashes tend to be sweeter and less watery, which is perfect for this recipe.

Can I add other vegetables to this recipe?

Definitely. Mushrooms, sun-dried tomatoes, or roasted red peppers would add wonderful depth and complement the butter and cheese. Just sauté them with the kale for best results.
