To prepare the filling heat some of the oil in a large pan over medium-high heat. Add diced onion and chopped bacon to the pan and cook until bacon is soft and the onions are translucent. Once done cooking, remove from heat and set aside.
Mix the cauliflower rice, cooked bacon, onion, dill, salt and pepper together in a large mixing bowl.
Remove the core from the cabbage and separate the leaves.
For the larger cabbage leaves, cut the leaf in half and remove the tough stem. For the smaller leaves, carefully slice the raised surface of the stem (keeping the leaf intact).
Depending on the size of your leaf, place approx. 1 tbsp of filling into the cabbage leaf and roll into a cone. Once rolled, use your thumb to push in the sides (this might take some practice, but don't worry it will work!). You can also secure the roll with a toothpick if your roll isn't secure enough.
Repeat until all of the filling and cabbage leaves are used up. This makes approx. 30-35 cabbage rolls. Save the too small or broken cabbage leaves to layer on the bottom of the instant pot.
Using some of the oil and grease the inside if your instant pot.
Use the remaining small or broken cabbage leaves to layer the bottom of the instant pot.
Tightly place all of the cabbage rolls into the instant pot. For the second layer, place the cabbage rolls in the alternate direction (this will help keep the cabbage rolls secure during the cooking process).
Once the cabbage rolls are placed in the instant pot, pour chicken broth or water over the rolls, along with the leftover olive oil.
Place 3-4 full slices of bacon over the cabbage rolls. Optional, but this will add extra flavor!
Add a plate on top of the cabbage rolls to secure them in place during the cooking process.
Lock the lid in place and select high pressure for 20 minutes. Once done cooking, turn to value to a quick release.
Holding the plate tightly to the cabbage rolls. strain the liquid from the pot, being careful to not drop any cabbage rolls. This step is optional but removing them from the liquid helps the cabbage rolls to set. You could alternatively just remove the cabbage rolls carefully with tongs.
Let the cabbage rolls cool for 15-20 minutes before serving.
Serve with sour cream, optional fried onions and enjoy!
