The perfect balance of tender beef and silky spaghetti squash—just 14 ingredients for a restaurant-worthy meal.
| Ingredient | Amount | Notes |

| Spaghetti Squash 🍠 | 2 whole | Medium-sized, halved lengthwise |
| Chuck Roast 🥩 | 1 ½ lb | Pre-cut into 1-inch cubes |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Olive Oil 🫒 | ½ cup | Extra-virgin, for searing |
| Beef Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Tomato Paste 🍅 | 2 tbsp | Smooth, not chunky |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Dried Rosemary 🌿 | ½ tsp | Crushed between fingers |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |

The spaghetti squash makes this dish special. Look for medium-sized ones—they're easier to handle and yield more strands. Costco or Trader Joe's usually carry good quality, but any grocery store will have them in season. Avoid squash with soft spots or cracks. The beef? Chuck roast is ideal—it's budget-friendly and stays tender. If you can't find pre-cubed, buy a whole roast and cut it yourself for even cooking. For the wine, any dry red works—Cabernet or Merlot are classic choices, but whatever's open in your fridge will do.
No red wine? Beef broth with a splash of balsamic vinegar works perfectly. Fresh thyme is ideal, but dried at one-third the amount is fine in a pinch. The tomato paste can be a squeeze tube from Trader Joe's—it's convenient and lasts months. If you're short on time, pre-minced garlic saves steps, but fresh is always better. For the squash, if you can't find spaghetti squash, butternut squash works too—just adjust the cooking time slightly. The Parmesan? Grate it fresh if possible—pre-grated gets clumpy and lacks flavor.
This dish reheats beautifully—3-4 minutes in the microwave or until warmed through. Store leftovers in the fridge for 4-5 days, or freeze for 3 months in airtight containers. I always make a double batch because it tastes even better the next day as the flavors meld. For meal prep, portion into containers with a sprinkle of Parmesan—ready to grab and heat whenever you need a quick, satisfying dinner.

Step-by-step instructions for beef and spaghetti squash
Here's the method for transforming tender chuck roast into rich beef and silky spaghetti squash threads.
Roast the Spaghetti Squash Until Tender
Preheat your oven to 400°F. Place the two halved spaghetti squash cut-side down on a parchment-lined baking sheet. Roast for 35-40 minutes until the flesh is fork-tender and the edges begin to brown slightly. The squash is ready when you can easily pierce it with a fork and the strands pull apart cleanly.
Here's the thing—don't overcook it. If you leave it too long, the squash will turn mushy instead of maintaining that perfect al dente texture. I like to check at the 30-minute mark and give it another 5-10 minutes if needed. Once done, transfer the squash to a cutting board and let it cool for 5 minutes before scraping out the strands with a fork.
Sear the Chuck Roast and Build the Flavor Base
Heat 0.25 cup of the olive oil in a large Dutch oven over medium-high heat. Add the 1.5 lb chuck roast cubes in a single layer and sear for 3-4 minutes per side until deeply browned. This step is crucial—it develops that rich, caramelized crust that carries so much flavor.
Remove the beef and set it aside. In the same pot, add the remaining 0.25 cup olive oil and the diced yellow onion. Cook for 5 minutes until softened and golden. Add the 4 cloves minced garlic and cook for another 30 seconds until fragrant. Stir in the 2 tbsp tomato paste, 1 tsp dried thyme, 0.5 tsp dried rosemary, 1.5 tsp salt, and 0.5 tsp ground black pepper.
Deglaze and Simmer the Beef
Pour in the 0.5 cup red wine and scrape up any browned bits from the bottom of the pot. Let it simmer for 2 minutes until the alcohol smell dissipates. Add the 1.5 cups beef broth and bring to a gentle boil. Return the beef to the pot, reduce heat to low, cover, and let it simmer for 1.5 hours.
During this time, the beef will become fork-tender and the sauce will reduce to a rich consistency. I check the sauce periodically and add a splash of water if it gets too thick. The beef is done when it easily pulls apart with two forks. Remove the beef and set it aside in the sauce, keeping it warm.
Combine the Beef with Spaghetti Squash
Once the beef is tender, use two forks to shred it into bite-sized pieces. Return the beef to the sauce and stir in the scraped spaghetti squash strands. The strands should soak up the rich beef sauce beautifully. Let the mixture simmer together for 5 minutes to meld the flavors.
Taste and adjust seasoning if needed. The squash will absorb some of the liquid, so if it seems too dry, add a splash of the reserved beef broth. The final dish should have a perfect balance of tender beef, silky squash, and robust sauce.
Garnish and Serve
Divide the beef and spaghetti squash mixture among four plates. Garnish each serving with 1 tbsp freshly grated parmesan cheese and 1 tbsp chopped fresh basil leaves. The parmesan adds a salty, umami depth, while the basil brightens the dish with its fresh, herbal notes.
Serve immediately while the squash is warm and the beef is juicy. Each bite should deliver a perfect harmony of tender beef, silky squash, and rich sauce. This dish is hearty enough to stand alone but pairs beautifully with a simple green salad or crusty bread to soak up any remaining sauce.
Pro Tips For Making Beef And Spaghetti Squash
- ROAST SQUASH HALVED-SIDE DOWN: Spaghetti squash loves its skin crispy—place halves cut-side down on the baking sheet first. This traps moisture inside while browning the exterior, so you end up with tender strands instead of a soggy mess. (Yes, even if it looks weird at first.)
- SEAR CHUCK IN BATCHES: A crowded pan steams the beef instead of searing it. Work in two batches over medium-high heat for 3-4 minutes per side—this builds flavor and prevents the chuck from turning into a sad, gray slab. I learned this the hard way when my first batch came out tasting like it was boiled.
- SALT THE SQUASH BEFORE ROASTING: Skip the salt until after slicing, and you’ll regret it—spaghetti squash needs a good 1/2 teaspoon of salt per half before hitting the oven. It crisps the skin better and seasons the flesh evenly. (Pro move: Sprinkle it on the cut sides too.)
- USE THE OVEN’S LOWEST RACK: Chuck roast needs space to breathe, and spaghetti squash hates being buried under hot air. Slide both trays onto the lowest oven rack—this guarantees even cooking and prevents the squash from drying out while the beef finishes. (Your thermometer will thank you.)
Perfect pairings for this beef and spaghetti squash
Classic Wine Pairings
A bold Cabernet Sauvignon from Napa Valley is my go-to choice—its rich tannins and dark fruit notes complement the beef's depth while standing up to the squash's natural sweetness. For a lighter option, try a Chianti Classico from Italy, where the bright acidity cuts through the dish's richness. 🍷
If you prefer red blends, a Zinfandel with its jammy berry flavors works beautifully, especially if your beef sauce has a touch of sweetness from the tomato paste. Avoid overly oaky whites like Chardonnay—they'll clash with the dish's hearty profile.
Craft Beer Complements
A malty amber ale with caramel and toasted notes bridges the gap between the beef and squash perfectly. I love Fat Tire from New Belgium—its balanced sweetness and bitterness mirror the dish's flavors. For something lighter, a wheat beer like Blue Moon adds a refreshing contrast.
If you're feeling adventurous, try a barleywine for its intense maltiness, which pairs surprisingly well with the dish's deep, savory elements. Just be sure to serve it chilled—room temperature barleywine can overwhelm the meal. 🍺
Unexpected Sauce Pairings
Drizzle with a balsamic glaze just before serving—its tangy sweetness enhances the beef's richness without overpowering the squash. I heat 2 tbsp balsamic vinegar with 1 tsp honey in a small saucepan until it thickens slightly, then drizzle over the top.
A dollop of whipped ricotta adds a creamy contrast that balances the dish's heartiness. Mix ½ cup ricotta with 1 tbsp lemon zest and a pinch of salt, then spoon it alongside each serving. The acidity brightens the beef's depth while the creaminess softens the squash's texture.
Seasonal Side Dishes
In summer, a cucumber-avocado salad with lime and cilantro provides the perfect refreshing counterpoint. Toss 2 cups diced cucumber with 1 avocado, 2 tbsp lime juice, and 2 tbsp chopped cilantro. The cool crunch cuts through the dish's richness beautifully. 🥒
For fall, roasted brussels sprouts with pancetta and balsamic glaze elevate the meal. Toss 1 lb halved brussels sprouts with 2 tbsp olive oil, 3 slices cooked pancetta, and roast at 425°F for 20 minutes. The salty, caramelized edges complement the beef's depth.
Bread Pairings
Crusty sourdough bread is ideal for soaking up any remaining sauce. Toast it lightly and rub with a garlic clove for extra flavor. I like to serve it warm with 1 tbsp softened butter and a sprinkle of flaky sea salt.
For a gluten-free option, try rosemary focaccia—its herby notes harmonize with the dish's savory profile. Look for pre-made versions at Whole Foods or Trader Joe's**, or make your own with olive oil, rosemary, and a pinch of salt. The crispy texture contrasts perfectly with the silky squash.

Frequently asked questions
Can I substitute ground beef for chuck roast in this recipe?
Yes, but the cooking time and method will change. Use 1 lb ground beef instead of cubed chuck roast and brown it thoroughly in the Dutch oven. Since ground beef cooks faster, reduce the simmering time to 30-40 minutes instead of 1.5 hours. The texture will be different but still delicious—just be sure to drain excess fat after browning.
How do I get the spaghetti squash strands to be more like real pasta?
The key is proper roasting and timing! Roast the squash at 400°F for 35-40 minutes until the flesh is tender but not mushy. Let it cool for 5 minutes before scraping with a fork—this helps the strands form more easily. If they're still too thick, roast the squash for an extra 5-10 minutes until fully tender.
Can I make this dish in a slow cooker?
Brown the beef and sauté the onions/garlic in a skillet first, then transfer everything to the slow cooker. Add the wine, broth, and seasonings, then cook on low for 6-7 hours or high for 3-4 hours. The squash can be roasted separately and added at the end—just toss it with the beef mixture and warm through for 5 minutes.
Why does my beef turn out dry when I cook it?
Overcooking or skipping the sear are the most common causes. Always brown the beef first to lock in moisture, then simmer on low heat with the lid on. If the dish seems dry, add a splash of beef broth or water to restore moisture. The squash should also be roasted until tender but not mushy—this helps balance the dish's texture.
What’s the best way to reheat leftovers?
Reheat in a skillet over medium-low heat with a splash of beef broth or water to keep it moist. Cover for 3-5 minutes until warmed through. Avoid microwaving—it can make the squash soggy. For extra flavor, add a pinch of salt and pepper while reheating, then garnish with fresh basil and Parmesan before serving.
