Heat 1 tbsp of butter in a large skillet over medium-low heat. Add diced onion and stir for 5-6 minutes until softened, then incorporate minced garlic and stir for one minute.
Incorporate sliced mushrooms and stir for 3 minutes to soften. Add minced meat and let it cook, stirring occasionally for 3-4 minutes.
Once the meat is pale brown, add heavy cream, salt, pepper, and Worcestershire sauce. Stir to combine and reduce heat to low. Let it simmer for 8-10 minutes to infuse flavors. Adjust salt as needed. In the meantime, cook the pasta following the product's instructions.
Mix one tbsp of cornstarch with 1 tbsp of hot water and pour it in. Stir over heat until it thickens. Repeat with an estra tbsp of slurry as needed for desired consistancy. (This step is important as your sauce will not thicken without the cornstarch slurry.)
Serve beef stroganoff over cooked noodles or incorporate the pasta with the beef stroganoff in the pan and enjoy!
TIPS
Store any leftover ground beef stroganoff in airtight containers within 2 hours of cooking.
