Method
Slow Cooker Method:
Prepare the Beef:
- Season the beef tips with salt and pepper, coat them in flour. In a large skillet, melt butter and sear the beef until browned. Transfer the beef to a plate.
Cook the Onions:
- In the same skillet, cook the diced onions for 2 minutes, scraping up the browned bits. Transfer the onions to the slow cooker.
Add Remaining Ingredients:
- Add the mushrooms, seasonings, bouillon, Worcestershire sauce, bay leaf, pepperoncinis, and beef stock into the slow cooker. Cover and cook on high for 3-4 hours or low for 6-7 hours.
Thicken the Gravy:
- Thirty minutes before the cook time is complete, whisk cornstarch with water and add it to the slow cooker. Cook until the gravy thickens.
Serve:
- Adjust seasoning with salt and pepper, and serve over mashed potatoes or rice.
Instant Pot Method:
Sear the Beef:
- Set the Instant Pot to "Sauté" mode. Season beef tips with salt and pepper, coat with flour, then sear in butter until browned. Remove the beef and set aside.
Cook the Onions:
- Add onions to the Instant Pot and cook for 2 minutes.
Add Remaining Ingredients:
- Add the beef back to the pot along with mushrooms, seasonings, bouillon, Worcestershire, pepperoncinis, and beef stock. Set the Instant Pot to "Pressure Cook" for 35 minutes.
Release Pressure & Thicken the Gravy:
- Allow pressure to release naturally for 10 minutes before quick release. If desired, thicken the gravy by adding cornstarch mixed with water and simmer on "Sauté" mode until thickened.
Serve:
- Adjust seasoning and serve.
Notes
- Slow Cooker Tip: Browning the beef and onions before adding them to the slow cooker deepens the flavor.
- Instant Pot Tip: Deglaze the pot to avoid the "Burn" notice.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
