In a shallow dish, sprinkle the meat cubes with flour, salt, pepper and paprika and toss well to coat. Set your instant casserole to "stir-fry" mode and melt the butter in the insert. Brown meat on all sides for 5 minutes, until golden brown.
Add the sliced mushrooms, sun-dried tomatoes, onion, garlic, Italian herbs and salt and pepper to taste. Cover with beef broth and white wine and put the lid on the instant pot, making sure the ventilation nozzle is in the unventilated position and set the timer for 15 minutes in “stew mode”.
Release the pressure, then remove the cap and put Instant Pot into “reheat” mode. Stir in half and half and mix until smooth. Adjust the seasoning if necessary with salt and pepper.
Serve over pasta, garnished with chopped parsley and grated Parmesan. Enjoy!
