Ingredients
• 2 lbs / 900g lamb shoulder
• 2 tbsp / 30g butter
• 1 cup / 240ml vegetable stock
• ¼ cup / 50g Swerve (or other granulated sweetener)
• ¼ cup / 60ml balsamic vinegar
• 3 garlic cloves, crushed
• 2 tbsp / 30ml soy sauce
• 1 tbsp / 15ml Dijon mustard
• 1 tsp / 5g salt
• 1 tsp / 1g dried sage
• ½ tsp / 0.5g freshly ground black pepper
Instructions
1. Directions
2. Set your Instant Pot to the ‘Sauté’ function and melt the butter in the inner pot. Add the crushed garlic and cook for about one minute until fragrant.
3. Pour in the soy sauce, balsamic vinegar, Dijon mustard, and Swerve. Stir continuously, allowing the sauce to bubble and combine for 2-3 minutes, then press ‘Cancel’.
4. Pat the lamb shoulder dry with paper towels and season it generously on all sides with the salt, pepper, and dried sage. Place the seasoned lamb into the pot with the sauce.
5. Pour the vegetable stock around the lamb. Secure the lid, turn the steam release handle to the ‘Sealing’ position.
6. Select the ‘Manual’ or ‘Pressure Cook’ button and set the timer to 35 minutes on high pressure.
7. Once the cooking cycle is complete, allow the pressure to release naturally for at least 10-15 minutes before performing a quick release for any remaining steam.
8. Carefully open the lid. Transfer the tender lamb shoulder to a serving platter. Drizzle generously with the rich balsamic sauce from the pot and serve immediately.

Pro Tips
• For a deeper flavor, sear the lamb shoulder in the hot butter on all sides before adding the garlic. Remove the lamb, create the sauce, then return the lamb to the pot to pressure cook.
• To create a thicker glaze, remove the cooked lamb and set the Instant Pot back to ‘Sauté’. Whisk in a slurry of 1 tbsp cornstarch and 2 tbsp cold water, simmering until the sauce thickens.
• This lamb is incredible served over creamy mashed potatoes, polenta, or cauliflower mash to soak up every last drop of the delicious sauce.
• Don’t be afraid to add herbs. A sprig of fresh rosemary or thyme tossed into the pot before cooking will add another layer of aromatic flavor.
