Remove the meat from the fridge and allow to rest for 10 minutes.
Add avocado oil to the Instant Pot. Set to Sauté, high and sear the meat for 3 minutes. Add the onion, for 2 minutes and the garlic for 1 further minute and cook until the meat is seared on all sides.
In a small bowl, stir together the seasoning ingredients. Sprinkle on top of the beef and stir.
Add the pepperoncini and brine. Add the sauerkraut (or giardiniera), peppers, courgettes and broth.
Set the Instant Pot to pressure cook, high for 35 mins. Allow the value to slow release for 10 minutes.
Remove most of the meat and veggies using a slotted spoon. Pull the meat apart with a fork so it shreds. It should be so tender it will do this easily.
Option to set the Instant Pot to sauté again and cook down the gravy to thicken. Option to add a little, about 1/4 tsp, of xanthan gum if you like a thicker gravy then add back in the veggie and meat and stir through. Adjust seasoning to taste.
Option for this Low Carb Italian Beef is to place in a hot oven for 10 - 15 minutes (400F), uncovered, before serving. This will get the meat nice and caramelized on top. It’s super tasty without though too.
Option to add some cheese too and melt in the oven or add some cheese to a cup in the microwave, cook for 30 secs- 1 min and pour over the beef once melted.
