When the evenings turn cool, few dinners feel as satisfying as a bowl of silky pasta tangled with roasted butternut squash. Add a shower of grated bottarga and a spoonful of nutty sage brown butter, and that cozy weeknight plate turns into something you would happily serve to guests. This butternut squash pasta with bottarga comes together in about 30 minutes, yet it tastes like a long autumn afternoon in a Sardinian kitchen.
Below you will find the full recipe, plus tips on choosing and grating bottarga so the finished dish sings with that deep, savory flavor the Mediterranean calls the caviar of the sea.
Why Bottarga and Butternut Squash Belong Together
Butternut squash is gently sweet and earthy. Bottarga, which is salt-cured and pressed grey mullet roe, is the opposite: intensely savory, briny, and rich with umami. Put them on the same fork and each one makes the other taste better. The squash softens bottarga's salinity, while the roe keeps all that sweetness from turning one-note.
Brown butter and fresh sage tie the two together. As butter cooks past melting, its milk solids toast and give off a hazelnut aroma that is pure autumn comfort. Bottarga is almost always added raw, off the heat, as a finishing ingredient, the same way Italians grate it over spaghetti. That final grating is where the magic happens.
Ingredients
This recipe serves four as a main course. You will need:
- 12 oz (340 g) dried pasta — spaghetti, linguine, or a short shape like casarecce all work
- 1 small butternut squash (about 1.5 lb), peeled and cut into 1/2-inch cubes
- 3 tablespoons olive oil, plus more for roasting
- 5 tablespoons unsalted butter
- 10–12 fresh sage leaves
- 1 small shallot, finely minced
- 1 clove garlic, thinly sliced
- Zest of 1 lemon, plus a squeeze of juice
- Bottarga, for grating — about 1 to 1.5 oz, or roughly 2 to 3 tablespoons once grated
- Freshly ground black pepper
- Salt, for the pasta water (go light; bottarga brings plenty)
Bottarga is the star here, so quality matters. We use Bottarga Esmeralda, a whole lobe of wild-caught grey mullet roe you can shave and grate to order, or the ready-to-use Bottarga Gold grated mullet roe in a resealable glass jar when you want the easiest possible finish.
How to Make Butternut Squash Pasta with Bottarga
Step 1: Roast the squash
Heat your oven to 425°F (220°C). Toss the cubed butternut squash with olive oil, a pinch of salt, and black pepper, then spread it on a sheet pan in a single layer. Roast for 20 to 25 minutes, turning once, until the edges are caramelized and the centers are tender. Caramelized edges add sweetness that plays beautifully against the salty roe.
Step 2: Boil the pasta
Bring a large pot of lightly salted water to a boil and cook the pasta until just shy of al dente. Reserve a full cup of the starchy cooking water before draining — you will use it to build the sauce.
Step 3: Make the sage brown butter
While the pasta cooks, melt the butter in a wide skillet over medium heat. Add the sage leaves and let the butter foam, swirling the pan. After 3 to 4 minutes it will smell nutty and turn golden brown. Add the shallot and garlic, cook for another minute until fragrant, then pull the pan off the heat.
Step 4: Bring it all together
Add the drained pasta, roasted squash, lemon zest, and about half the reserved pasta water to the skillet. Toss over low heat, adding more pasta water a splash at a time, until a glossy sauce coats every strand. Finish with a small squeeze of lemon juice.
Step 5: Finish with bottarga
Plate the pasta, then grate the bottarga generously over each bowl using a microplane or fine grater. Do not stir it in over heat — the raw grating on top is what delivers the briny, aromatic punch. A final crack of black pepper, and dinner is served.
How to Choose and Grate Good Bottarga
Grey mullet bottarga (bottarga di muggine) is prized for its smooth, slightly waxy texture and clean, oceanic flavor. Look for roe that is amber to deep orange, firm, and free of a harsh or fishy smell. A whole lobe keeps beautifully wrapped in the refrigerator and can be shaved or grated as needed, which is why many cooks prefer it for both pasta and crostini.
If you would rather skip the grating, pre-grated bottarga in a jar is a genuine shortcut — keep it in the fridge and finish dishes straight from the spoon. Either way, remember bottarga is naturally salty, so taste before you add extra salt anywhere else. Explore the full range in our bottarga collection, and pair it with a quality dried pasta from our Italian gourmet pasta selection.
Easy Variations
- Add greens: Toss in a handful of baby kale or spinach with the squash for color and body.
- Make it crunchy: Top with toasted breadcrumbs or chopped walnuts for contrast.
- Go richer: A spoonful of ricotta stirred in at the end turns this into a creamier, more indulgent bowl.
- Swap the shape: Gnocchi or ravioli also love sage brown butter and a grating of bottarga.
Frequently Asked Questions
What does bottarga taste like?
Bottarga is deeply savory and briny, with a concentrated umami flavor often compared to a cross between anchovy and aged cheese. A little goes a long way, which makes it ideal as a finishing ingredient.
Can I cook bottarga?
It is best added raw, off the heat. High heat dulls its delicate aroma, so grate or shave it over a finished dish rather than stirring it into a hot pan.
How do I store bottarga?
Keep a whole lobe wrapped tightly in the refrigerator, where it will last for months. Grated bottarga in a jar also stores in the fridge; just reseal it after each use.
Can I make this pasta ahead of time?
Roast the squash and brown the butter earlier in the day, then reheat gently and toss with freshly cooked pasta. Always grate the bottarga fresh, right before serving.
