Preparation Steps
- Pat the stewing beef dry with paper towels and season with salt and pepper. In a skillet, heat oil and sear beef in batches, about 3-4 minutes per side.
- Reduce heat and add half the butter to the skillet. Add onions and garlic, cooking until fragrant, about 4-5 minutes.
- Sprinkle flour over onion and garlic, stir to form a roux. Cook for 2 minutes until golden, then whisk in Dijon mustard and beef stock gradually.
- Transfer roux mixture to slow cooker, add seared beef, stir to combine, and cook on LOW for 8 hours or HIGH for 5 hours.
- In the last 30 minutes, melt remaining butter in a skillet, add mushrooms and garlic, season, and sauté until golden brown, about 5-6 minutes.
- Mix sour cream with cooking liquid until smooth. Return to slow cooker with sautéed mushrooms, stir, and warm through for 5-10 minutes before serving.

Notes
Sear beef for enhanced flavor, avoid boiling after adding sour cream, and store leftovers in airtight containers for up to 3 days.
