Set Instant Pot to saute. When it says HOT, add oil.
Add ground beef, onions and garlic to pot. Cook until meat is browned, stirring to break up meat. Season with salt, pepper, thyme and Worcestershire sauce as it is cooking.
Add tomato paste, water and beef base. Stir to scrape up any bits stuck to the bottom of the pot. Add elbows. Press cancel to stop Saute.
Lock lid in place and seal valve. Cook on high pressure for 4 minutes. (Cook time may vary with the kind of pasta you choose to use). Quick release the pressure. Stir in half of the cheese. Serve remaining cheese on the side.
Put 1 cup of water into bottom of Instant Pot. Put sausages into water or onto trivet. (Mine were frozen and I put right into the water.) Cook on high pressure for 1 minute. Let pressure naturally release for 10 minutes or so.
Remove sausages from the pot, but leave cooking water in the pot for additional flavor.
Add all remaining ingredients to pot. Pressure cook for 5 minutes. Let pressure naturally release for 10 minutes or so.
Meanwhile, slice the sausage. You can either add it to the sauce or serve it on the side. I chose to serve it with some pasta and Parmesan.
Stir and taste; add additional seasoning, if desired.
Use just a little butter to grease 2 silicone cups. (You can make more than this if you would like. The time will remain the same.)
Put 1 cup of water in the bottom of your Instant Pot, then put a rack in the pot. Place the silicone cups on top of the rack.
Crack 1 egg in each of the silicone cups. Salt & pepper if desired.
Put on lid, seal and set valve to "sealing". Set time for 2 minutes high pressure by pressing the Manual button, the Pressure Cook button or the Egg button and adjusting the time using the + and - buttons.
When the 2 minutes is up, leave the lid on and let it naturally release pressure for 3 minutes.
Manually release remaining pressure and remove lid. Use tongs to remove silicone cups from pot and place carefully onto plate.
The eggs should slide right out of the silicone cup onto your plate. Some brands of silicone cups require you to loosen the egg a bit with a spoon.
Set Instant Pot to saute. Wait for it to heat up (it will say "hot").
Season meat on both sides with salt and pepper. Add a little oil to the pot and sear meat for 10 minutes per side.
Hit cancel button.
Add 1 1/2 cups water to pot, along with the remaining ingredients. Set to manual pressure for 60 minutes. When time is up, release pressure naturally for 20 minutes.
If you have a 3 lb. roast, cook for 75 minutes. You don't need to change anything else.
If you would like, you can make a gravy from the broth. Remove the roast and put on a platter. Set the Instant Pot to saute. Combine a couple tablespoons of cornstarch or potato starch with enough water to make a thin paste. Drizzle it into the broth as you whisk continuously, until thickened.
This recipe will work with any of the Instant Pots, even the 3 quart Mini. Press the saute button on your Instant Pot. Wait for it to heat up (it will say "hot"), then add the butter and garlic cloves. Lightly brown the garlic and the butter.
While that is cooking, peel your potatoes (if desired). Cut your potatoes into halves or quarters lengthwise, depending on the size of the potato, and cut into rough 1/2" slices.
Turn the Instant Pot off by hitting the cancel button. Add the half & half. Add the potato pieces and season generously with salt and pepper. Close the Instant Pot, make sure the release valve is set to "sealing", and press the "manual" or "pressure cook" button and set the time to 8 minutes, using the + and - buttons.
Once the cooking time is up, turn the pot off and release the pressure manually. Open the pot. It won't be a pretty sight.
Mash everything with a potato masher. Taste and season with more salt & pepper, if needed.
