• Beef broth: 1 cup, for a deep, savory base
• Dry white wine: ½ cup (optional, but highly recommended)
• Bay leaves: 2
• Fresh thyme: 4-5 sprigs
• Fresh rosemary: 2 sprigs
• Salt and pepper: To taste
• Gremolata (optional, for garnish): A mixture of lemon zest, garlic, and parsley

Instruction Guide

Here’s the step-by-step process, broken down to make it super easy to follow:

1. Prep The Beef

   • Pat the beef shanks dry with paper towels.
   • Season generously with salt and pepper.
   • Dredge lightly in flour, shaking off excess.

2. Brown The Beef

   • Heat olive oil in a skillet over medium-high heat.
   • Sear the shanks for 3-4 minutes per side until golden brown.
   • Transfer the beef to the slow cooker.

3. Sauté The Vegetables

   • In the same skillet, add onions, carrots, and celery.
   • Cook for 5 minutes until softened.
   • Add garlic and tomato paste; cook for 1-2 more minutes.

4. Deglaze

   • Pour in the wine (if using) and scrape the bottom of the pan to release all the flavorful browned bits.

5. Combine In The Slow Cooker

   • Transfer the vegetables and liquid to the slow cooker.
   • Add crushed tomatoes, beef broth, bay leaves, thyme, and rosemary.
   • Nestle the browned beef shanks into the sauce.

6. Cook Low And Slow

   • Cover and cook on low for 7-8 hours or on high for 4-5 hours.
   • The beef should be fork-tender, and the sauce thick and aromatic.

7. Finish And Serve

   • Remove bay leaves and herb stems.
   • Adjust seasoning with salt and pepper.
   • Serve hot with gremolata on top and a side of creamy polenta, mashed potatoes, or pasta.

Ingredient Swaps

Don’t worry if you don’t have everything on hand; there are plenty of substitutions:

• Beef shanks → Short ribs for a richer, fattier flavor
• White wine → Red wine or extra beef broth if you prefer alcohol-free
• Celery → Fennel for a slightly sweeter, aromatic note
• Crushed tomatoes → Tomato puree if you want a smoother sauce
• Fresh herbs → Dried herbs (use about 1/3 of the amount called for)

Helpful Tips

Make your Osso Buco even better with these tricks:

• Don’t skip browning the beef: It locks in flavor and adds color.
• Low and slow is key: Resist the temptation to speed it up. The longer cooking time gives the beef that melt-in-your-mouth texture.
• Marrow magic: If your shanks have marrow, scrape it into the sauce-it’s liquid gold.
• Prep ahead: You can chop vegetables the night before and store them in the fridge.

Customization Ideas

Make this dish uniquely yours:

• Spicy kick: Add a pinch of red pepper flakes to the sauce.
• Herbal twist: Experiment with sage or oregano instead of rosemary.
• Vegetable boost: Toss in mushrooms or bell peppers for extra texture.
• Creamy finish: Stir in a tablespoon of butter or a splash of cream at the end for a richer sauce.
