Easy Spaghetti Squash with Cheese and Pepper is a simple dinner that turns one medium roasted squash into four servings of tender, pasta-like strands coated in sharp Pecorino Romano, optional Parmesan, and plenty of freshly ground black pepper. Roast the squash at 400°F for 40–50 minutes, scrape it into strands, then toss it with the cheese and a few tablespoons of hot water until lightly creamy.
This cacio e pepe-style squash is savory, peppery, salty, and satisfying without feeling heavy. The squash becomes tender and moist in the oven, while hot strands help the freshly grated cheese melt into a delicate coating that tastes wonderfully similar to the classic Roman pasta.

This recipe delivers the comfort of cacio e pepe with a vegetable-based foundation. Instead of boiling pasta, you roast spaghetti squash until its flesh pulls into long, tender strands that are ready to catch every bit of salty cheese and fragrant pepper.
The ingredient list is short, but each item matters. Pecorino Romano brings the characteristic sharp and salty flavor, olive oil helps season the squash as it roasts, and hot water loosens the cheese into a light coating rather than a dry sprinkle.
It is also a practical dinner for busy evenings. The squash cooks mostly unattended, and the final tossing step takes only a few minutes once the strands are ready.

Ingredients You’ll Need
Choose a medium spaghetti squash weighing about 3 pounds. The shell should feel firm and free from soft spots, and the squash should feel heavy for its size.
- Spaghetti squash: One medium squash creates four generous side or dinner portions.
- Extra-virgin olive oil: One tablespoon coats the cut sides and helps the salt and pepper cling during roasting.
- Kosher salt: Use 1/2 teaspoon before roasting, then add more after the cheese is mixed in if needed.
- Black pepper: One teaspoon is divided between roasting and finishing. Freshly ground pepper gives the strongest aroma.
- Pecorino Romano: Three-fourths cup, finely grated, provides the main flavor and creamy cheese base.
- Parmesan: Two tablespoons are optional, but they add a slightly mellow, nutty note alongside the Pecorino.
- Hot water: Keep 2–4 tablespoons available to loosen the cheese coating one tablespoon at a time.
Freshly grate both cheeses immediately before using. Pre-shredded cheese often contains anti-caking ingredients that can prevent it from melting smoothly and may leave clumps or stringy pieces.
How to Make It Step-by-Step
Step 1: Heat your oven to 400°F and line a baking sheet with parchment paper. The parchment makes cleanup easier and helps protect the squash from sticking as its natural sugars caramelize.
Step 2: Carefully cut the spaghetti squash in half lengthwise, then scoop out the seeds and stringy pulp with a sturdy spoon. If the squash is difficult to cut, microwave it whole for about 4–5 minutes first, allowing it to cool enough to handle safely before slicing.
Step 3: Brush the cut sides with the olive oil, then sprinkle them with the kosher salt and about 1/2 teaspoon of the freshly ground black pepper. Seasoning before roasting gives the squash a flavorful foundation rather than leaving all the seasoning on the surface at the end.
Step 4: Arrange the halves cut-side down on the parchment-lined baking sheet. Roast for 40–50 minutes, checking toward the end of the cooking time, until the shell can be pierced easily and the flesh separates into strands.
Step 5: Remove the squash from the oven and let it cool for a few minutes so it is easier to handle. Use a fork to scrape lengthwise through the flesh, separating it into spaghetti-like strands and transferring them to a large bowl.
Step 6: While the squash is still hot, add the finely grated Pecorino Romano, Parmesan if using, and the remaining 1/2 teaspoon of black pepper. Toss gently off the heat, because excessive direct heat can cause the cheese to seize instead of forming a smooth coating.
Step 7: Add hot water or reserved squash-cooking liquid one tablespoon at a time, tossing after each addition. Stop when the cheese clings lightly to the strands and looks creamy without becoming watery, then taste and adjust the salt and pepper.
Step 8: Divide the squash among four bowls and serve immediately. Finish each portion with additional Pecorino Romano and a final grind of black pepper for a bright, savory bite.
Chef Tips for Creamy Cacio e Pepe Squash
The best texture comes from combining hot squash with finely grated cheese. Warm strands help soften the Pecorino, while a small amount of hot water gives the cheese enough moisture to coat the squash.
Add the water gradually rather than pouring in all 2–4 tablespoons at once. Spaghetti squash can vary in moisture, so your squash may need only a tablespoon or two to reach the right consistency.
Keep the bowl off the burner during the cheese step. Direct heat can make Pecorino tighten into rubbery clumps, so let the residual heat from the roasted squash do most of the work.
Pecorino Romano should remain the main cheese. Parmesan is a useful supplement, but replacing all the Pecorino would remove the sharper, saltier character that makes this dish taste like cacio e pepe.
For the longest strands, scrape the fork lengthwise along the squash rather than stirring vigorously. A gentle toss at the end preserves the strands and distributes the cheese evenly.
Serving Suggestions
Serve this squash as a light main course with a crisp green salad, roasted vegetables, or warm crusty bread. It also works beautifully as a side dish with roasted chicken, fish, or sautéed greens.
Because the dish is rich with cheese but still vegetable-forward, keep additional toppings simple. Extra Pecorino and black pepper are all it needs, although a few fresh herbs can add color if you have them available.
For a larger Italian-inspired meal, serve it before or alongside homemade cheese enchiladas when you are planning a cheese-loving family dinner. The squash is also a useful option when you want something warm and filling without a traditional pasta dish.
Storage and Reheating
This dish is best served immediately because the cheese coating is at its smoothest while the squash is hot. If you have leftovers, place them in an airtight container and refrigerate them for up to 3 days.
Reheat gently in a skillet or microwave, adding a small splash of water if the strands look dry. Use low to moderate heat and stir carefully, since aggressive heat may cause the cheese to tighten.
For the freshest texture, grate a little more Pecorino over the reheated squash and add a fresh grind of black pepper. The strands may be slightly softer after refrigeration, but the flavor remains savory and satisfying.
Common Questions
Can I use only Parmesan? Parmesan can be included, but it should not replace all of the Pecorino Romano if you want the characteristic sharp, salty cacio e pepe flavor. Use the optional 2 tablespoons of Parmesan as a supplement.
Can I prepare the squash ahead? You can roast and scrape the squash earlier in the day, then warm the strands before adding the cheese. Mix in the Pecorino only when you are ready to serve for the smoothest coating.
Why did my cheese clump? The squash may not have been hot enough, the cheese may have been too coarsely grated, or the mixture may have been exposed to direct heat. Finely grate the cheese, toss off the heat, and add hot water gradually.
Is the skin edible? The roasted shell is not part of this recipe. Scrape out the tender flesh and discard the shell after it has cooled enough to handle.
