This hearty Short Rib Ragu with Parmesan Mashed Potatoes has become my go-to comfort dish for special family dinners. The meltingly tender beef combined with creamy, cheese-laden potatoes creates a restaurant-quality meal that always draws everyone to the table with anticipation.
I first prepared this dish for my husband's birthday dinner last winter, and it has since become our most requested meal when we have guests. The look of pure joy on everyone's faces when they take that first bite makes the long cooking time completely worthwhile.
Ingredients
- For the Short Rib Ragu: 3-4 pounds beef short ribs bone-in. Choose ribs with good marbling for the most tender result
- 1 tablespoon olive oil: Use extra virgin for best flavor
- 1 large onion chopped: Sweet varieties like Vidalia add nice depth
- 2 cloves garlic minced: Fresh is essential here for authentic flavor
- 2 carrots peeled and chopped: Look for firm bright orange ones
- 2 celery stalks chopped: The leaves add extra flavor if you have them
- 2 cups crushed tomatoes canned: San Marzano tomatoes provide the richest flavor
- 1 cup beef broth: Homemade is best but high-quality store-bought works well
- 1 teaspoon dried thyme: Rub between your fingers to release oils before adding
- 1 teaspoon dried rosemary: Same technique as the thyme
- 1 bay leaf: Always remember to remove before serving
- Salt and pepper to taste: Sea salt and freshly ground pepper make a difference
- 1 tablespoon tomato paste: This concentrated flavor booster is crucial
- Fresh parsley for garnish optional: Adds brightness to the finished dish
- For the Parmesan Mashed Potatoes: 2 pounds russet potatoes peeled and chopped. These make the fluffiest mashed potatoes
- 1/2 cup unsalted butter: European-style butter has a higher fat content for extra richness
- 1/2 cup milk: Whole milk creates the creamiest texture
- 1/2 cup grated Parmesan cheese: Freshly grated from a block tastes significantly better
- Salt and pepper to taste: Be generous with both
- Fresh parsley for garnish optional: A little green brightens the presentation
Step-by-Step Instructions
- Brown the Short Ribs:
- Season your short ribs generously with salt and pepper on all sides. Heat olive oil in a large Dutch oven over medium-high heat until shimmering. Place the ribs in carefully without crowding the pot you may need to work in batches. Sear each side for about 2-3 minutes until they develop a deep brown crust. This crucial step creates the foundation of flavor for the entire dish. When properly browned remove and set aside on a plate.
- Sauté the Vegetables:
- Reduce heat to medium and add your chopped onion carrots and celery to the same pot using the beef fat left behind. Cook for 5-7 minutes stirring occasionally until the vegetables soften and the onions become translucent. Add the minced garlic and cook for another minute until fragrant but not browned as garlic can quickly become bitter.
- Build the Sauce Base:
- Add tomato paste to the vegetable mixture and cook for 2-3 minutes stirring constantly until it darkens slightly and begins to stick to the bottom of the pot. This caramelizes the sugars in the paste developing deep umami flavor. Pour in the crushed tomatoes and beef broth scraping the bottom of the pot with a wooden spoon to release all those flavorful browned bits.
- Add Herbs and Braise:
- Sprinkle in the dried thyme and rosemary and add the bay leaf. Return the browned short ribs to the pot nestling them into the sauce so they're mostly submerged. Bring to a gentle simmer then reduce heat to low cover with a tight-fitting lid and let braise undisturbed for 3-4 hours. The meat is ready when it easily falls off the bone when prodded with a fork.
- Prepare the Potatoes:
- About 30 minutes before the ragu is finished place peeled and chopped potatoes in a large pot and cover with cold water by an inch. Add a generous pinch of salt and bring to a boil. Cook for 15-20 minutes until the potatoes are completely tender when pierced with a knife they should offer no resistance.
- Finish the Ragu:
- Once the short ribs are perfectly tender remove them from the sauce onto a cutting board. When cool enough to handle shred the meat with two forks discarding bones and any tough connective tissue. Return the shredded meat to the pot and stir to combine with the sauce. Taste and adjust seasonings adding more salt and pepper if needed.
- Make Parmesan Mashed Potatoes:
- Drain the cooked potatoes thoroughly and return them to the hot pot. Let them sit for a minute to allow excess moisture to evaporate. Add butter and let it melt into the hot potatoes. Pour in warm milk and mash until smooth and creamy using a potato masher or ricer for best texture. Fold in the grated Parmesan until completely incorporated and season generously with salt and pepper.
- Serve and Garnish:
- Spoon a generous portion of the Parmesan mashed potatoes onto each plate creating a small well in the center. Ladle the hot short rib ragu over the potatoes allowing the sauce to pool around the edges. Sprinkle with fresh parsley if desired and serve immediately while piping hot.

My absolute favorite ingredient in this recipe is the Parmesan cheese in the mashed potatoes. I discovered this trick years ago from my Italian grandmother who would never serve plain mashed potatoes. She always said "If you want to know if someone can really cook watch how they make the simplest things" and these potatoes are proof of that wisdom.
Storage and Reheating
The short rib ragu actually improves with time making it an excellent make-ahead dish. Store it in an airtight container in the refrigerator for up to 4 days. When refrigerated the fat will rise to the top and solidify which you can easily remove before reheating for a lighter dish. To reheat place in a saucepan over medium-low heat adding a splash of beef broth if it seems too thick and stir occasionally until bubbling.
The mashed potatoes are best made fresh but can be stored separately for up to 2 days. Reheat them gently in the microwave or in a double boiler with a splash of milk or cream to bring back their creamy texture. Never reheat mashed potatoes on direct high heat as they can scorch easily.
Ingredient Substitutions
While this recipe is perfect as written you can make several adaptations based on what you have available. Boneless short ribs work well though you miss some of the richness that bones provide. Chuck roast cut into large chunks makes an excellent substitute for short ribs with similar results.
For the mashed potatoes Yukon Gold potatoes can replace russets for a naturally buttery flavor. If you prefer a lighter version use half cauliflower and half potatoes. Greek yogurt can substitute for some of the butter and milk for a tangy twist. Romano or Grana Padano cheese works beautifully in place of Parmesan.
Serving Suggestions
This hearty dish stands perfectly on its own but can be elevated with thoughtful accompaniments. A simple arugula salad dressed with lemon juice and olive oil provides refreshing contrast to the rich ragu. Crusty bread is essential for soaking up every last bit of the delicious sauce.
For a complete dinner party menu start with a light antipasto platter followed by this substantial main course and finish with a simple dessert like affogato or berries with whipped cream. A medium-bodied red wine such as Chianti Classico or Montepulciano d'Abruzzo pairs beautifully with the rich flavors of this dish.
Recipe Q&A
- → Can I make this dish in a slow cooker?
Yes! After browning the short ribs and sautéing the vegetables on the stovetop, transfer everything to a slow cooker. Cook on low for 7-8 hours or high for 4-5 hours until the meat is fork-tender and falling off the bone.
- → What can I substitute for beef short ribs?
Beef chuck roast, brisket, or even oxtail make excellent substitutes for short ribs in this dish. Just adjust cooking times accordingly as larger cuts may need additional time to become tender.
- → Can I make this ahead of time?
Absolutely! The ragu actually improves in flavor when made 1-2 days ahead. Store the ragu and mashed potatoes separately in refrigerator-safe containers, then reheat gently before serving. The ragu can also be frozen for up to 3 months.
- → What sides pair well with this dish?
A simple green salad with vinaigrette, roasted asparagus, or sautéed green beans complement this rich dish beautifully. Crusty bread is also excellent for soaking up the flavorful sauce.
- → How can I make this dish dairy-free?
For dairy-free mashed potatoes, substitute the butter with olive oil, the milk with unsweetened almond or oat milk, and omit the Parmesan cheese. You can add nutritional yeast for a cheesy flavor or simply season with more herbs and garlic.
- → What wine pairs best with short rib ragu?
A full-bodied red wine like Cabernet Sauvignon, Merlot, or Syrah complements the richness of the short ribs beautifully. The tannins in these wines cut through the fat and enhance the savory flavors of the dish.
