Pro Tips
• For a deeper, richer flavor, use the ‘Sauté’ function on your Instant Pot to sear the lamb racks in olive oil on all sides before pressure cooking.
• For a creamier sauce, stir the sour cream directly into the pot after cooking. Ensure the pot is on the ‘Keep Warm’ setting, not ‘Sauté’, to prevent curdling.
• Feel free to use fresh herbs. A good rule of thumb is to use one tablespoon of fresh chopped herbs for every teaspoon of dried herbs called for in the recipe.
• For more even cooking and better flavor absorption, halve larger Brussels sprouts and mushrooms before adding them to the pot.
