Whole30 Beef Stroganoff

For the Coconut Sour Cream:
1 The day before cooking, place an unshaken and sealed can of full-fat coconut milk in the fridge. The following day, open the can and spoon off the solidified cream. Add cream to a bowl along with the juice of one lemon. Whisk until smooth and creamy. Taste for seasoning and adjust lemon juice as required. Cover bowl with wrap and return coconut to fridge until ready to serve.
For the Beef Stroganoff:
1 Preheat a 12” stainless-steel or cast-iron skillet over high heat. Add avocado oil and let heat 30 seconds. Add steak and cook undisturbed 2-3 minutes. Flip steak slices and cook an additional 1 minute. Transfer browned steak to a bowl and set aside.
2 Return pan to stovetop and lower heat to medium. Add ghee and mushrooms and season with a pinch of salt. Sauté mushrooms 4-5 minutes and scrape any brown bits on the bottom of the pan.
3 Once mushrooms have browned and their moisture has evaporated, add shallots and garlic. Sauté an additional 2-3 minutes. Add chicken stock to deglaze pan. Cook an additional 30 seconds or until stock has reduced by ¼.
4 Add 1 cup coconut ‘sour cream’, mustard and a pinch of black pepper, stir to combine. Gently simmer the sauce for 2-3 minutes. Taste for seasoning and adjust salt and pepper as required.
5 Return beef to pan and toss to coat. Remove from heat, add dill and toss everything to combine.
6 Serve overtop of mashed potatoes and garnish with more fresh dill.
