How to Make Easy Lamb Shanks with Mushroom-Infused Tomato Sauce (Instant Pot, Crockpot, or Oven Braising) Recipe
Step 1: Season and Sear the Lamb Shanks
Start by seasoning the lamb shanks generously with Magic Mushroom Powder or kosher salt. Then, heat a tablespoon of ghee or olive oil in your cooking vessel—Instant Pot, skillet, or Dutch oven—and sear the shanks in batches until they’re beautifully browned on all sides, about 8 to 10 minutes. This step locks in flavor and adds fantastic depth to your sauce. No worries if you’re short on time; skipping the sear means the shanks will still turn out delicious!
Step 2: Build the Flavor Base with Vegetables
After removing the lamb, add the remaining ghee or oil to the pot and toss in chopped onion, carrot, and celery. Season lightly with Magic Mushroom Powder and cook until the veggies have softened, releasing their natural sweetness. Next, stir in the tomato paste and smashed garlic cloves, cooking just until fragrant to develop a rich, savory foundation for the sauce.
Step 3: Combine Ingredients and Cook
Return the seared lamb shanks to the pot and add bone broth, aged balsamic vinegar, and fish sauce. Pour diced tomatoes on top and nestle fresh herb sprigs and bay leaves into the mix. Secure the lid and set your chosen cooking method: 45 minutes on high in the Instant Pot, 8-10 hours on low in the Crockpot, or braise in a 300°F oven covered for 3-4 hours. Each technique brings out the tender, fall-off-the-bone magic you crave.
Step 4: Finish the Sauce and Serve
Once cooking is complete and the lamb is beautifully tender, remove the herb sprigs and bay leaves. Use an immersion blender to puree the braised vegetables into the sauce, thickening it to luscious perfection. Taste and adjust seasoning with Magic Mushroom Powder, salt, and freshly ground black pepper. Finally, ladle that glorious mushroom-infused tomato sauce over the shanks and sprinkle with fresh Italian parsley if you like a bright finishing touch.
How to Serve Easy Lamb Shanks with Mushroom-Infused Tomato Sauce (Instant Pot, Crockpot, or Oven Braising) Recipe
Garnishes
A sprinkle of minced Italian parsley adds a fresh pop of color and a light, herbaceous note that contrasts beautifully with the richness of the lamb. If you want an extra punch, a little lemon zest or a drizzle of high-quality olive oil can brighten the entire dish wonderfully.
Side Dishes
This hearty dish pairs beautifully with creamy mashed potatoes, polenta, or even buttery mashed cauliflower for a low-carb alternative. A side of sautéed greens or roasted root vegetables can add essential texture and balance, bringing both comfort and variety to your plate.
Creative Ways to Present
Serve the lamb shanks on a rustic wooden board or a vibrant ceramic plate to highlight their golden crust and rich sauce. Use the sauce as a base on the plate, nestling the lamb right on top for a restaurant-quality presentation. Garnish with whole herb sprigs or even edible flowers for an extra special touch when entertaining.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftover lamb shanks and sauce together in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen as they rest, making for an even more delicious meal the next day.
Freezing
This recipe freezes beautifully. Package the lamb shanks and sauce separately or together in freezer-safe containers or heavy-duty zip bags and freeze for up to 3 months. Just be sure to leave some room for sauce expansion.
Reheating
Reheat gently in a covered skillet over low-medium heat or in the oven wrapped in foil to keep the meat moist. Avoid microwaving if possible, as slow, steady reheating preserves tenderness and texture best.
FAQs
-
Can I skip searing the lamb shanks?
Yes! Searing adds a lovely caramelized flavor and richer color, but if you’re pressed for time, you can skip this step. The lamb will still cook to tender perfection and taste delicious thanks to the deep flavors infused during braising.
-
What if I don’t have Magic Mushroom Powder?
If you don’t have Magic Mushroom Powder, seasoned salt or even a touch of soy sauce can help add umami to the dish. The recipe will remain flavorful, though the unique mushroom depth might be subtle.
-
Can I use frozen lamb shanks?
Absolutely! Just be sure to thaw them completely before cooking to ensure even cooking, especially when braising in the oven or slow cooker. Instant Pots can handle frozen meat but will require longer cook times.

Ingredients
Lamb and Seasoning
- 3 pounds lamb shanks
- Magic Mushroom Powder or Diamond Crystal kosher salt, to taste
- Freshly ground black pepper, to taste
Cooking Fats
- 2 tablespoons ghee or extra virgin olive oil, divided
Vegetables
- 1 large onion, roughly chopped
- 2 medium carrots, roughly chopped
- 2 celery stalks, roughly chopped
- 3 garlic cloves, smashed and peeled
Other Ingredients
- 1 tablespoon tomato paste
- ½ cup bone broth (plus 2 cups if oven braising)
- 1 tablespoon aged balsamic vinegar
- 1 teaspoon Red Boat fish sauce
- 14 ounces canned diced tomatoes, drained or 1 pound Roma tomatoes, diced
- 3 fresh thyme sprigs or 1 fresh rosemary sprig
- 2 dried bay leaves
Garnish
- ¼ cup minced Italian parsley (optional)
Instructions
- Season the Lamb Shanks: Generously season the lamb shanks with Magic Mushroom Powder or Diamond Crystal kosher salt and freshly ground black pepper to ensure savory depth.
- Sear the Lamb Shanks: Heat 1 tablespoon of ghee or extra virgin olive oil in your chosen cooking vessel (Instant Pot on sauté function, skillet, or Dutch oven) over medium-high heat. Sear lamb shanks in batches for about 8 to 10 minutes until browned on all sides. If short on time, this step can be skipped but adds significant flavor. Remove the browned shanks and set aside on a platter.
- Sauté the Vegetables: Add the remaining tablespoon of ghee or olive oil to the empty pot or skillet. Toss in chopped onions, carrots, and celery. Season lightly with Magic Mushroom Powder. Cook until the vegetables soften, about 3 to 5 minutes. Stir in tomato paste and smashed garlic cloves, cooking until fragrant to build a rich base.
- Add Liquid Ingredients and Herbs: Return the lamb shanks to the cooking vessel. Pour in bone broth (½ cup for Instant Pot/Crockpot, 2 cups for oven braising), aged balsamic vinegar, fish sauce, and drained diced tomatoes. Tuck in sprigs of fresh thyme or rosemary and bay leaves to infuse savory and herbal notes.
- Cook the Lamb Shanks: For Instant Pot: Lock the lid and set to cook on high pressure for 45 minutes. Allow pressure to release naturally or manually after 20 minutes. For Crockpot: Transfer sautéed vegetables and lamb to slow cooker. Cover and cook on low for 8 to 10 hours or on high for 5 to 6 hours. For oven braising: Preheat oven to 300°F, bring contents to boil on stovetop, cover, then place in oven for 3 to 4 hours until meat is fork tender.
- Finish the Sauce: Remove the herbs from the sauce. Use an immersion blender directly in the pot to puree the vegetables and thicken the sauce to a rich consistency.
- Adjust Seasoning and Serve: Taste the sauce and adjust seasoning with Magic Mushroom Powder, salt, and pepper as needed. Plate the lamb shanks, ladle the thickened sauce over them, and sprinkle with minced Italian parsley if desired for freshness and color.
Notes
- If using a slow cooker or crockpot, sear the lamb shanks and sauté vegetables in a skillet before transferring to the slow cooker for best flavor development.
- If short on time, searing the lamb shanks can be omitted, but it improves color and taste significantly.
- For oven braising, increase the bone broth quantity to 2 cups to ensure sufficient liquid during the longer cooking time.
- Using fresh herbs like thyme or rosemary is recommended for optimal flavor but dried bay leaves are essential in all methods.
- Adjust the cooking time based on the tenderness needed; lamb shanks become perfectly tender when the meat easily falls off the bone.
