French Onion Slow Cooked Beef has flavors reminiscent of the much-loved French onion soup. This slow cooked beef can be made ahead for a cozy weeknight meal or cooked on the weekend for a night in with family or friends. Chunks of beef are gently cooked for a couple of hours with caramelized onions, fresh thyme & wine then topped with baguette slices & Gruyere cheese. I like to serve this with roasted carrots & salad green or steamed beans. If you want to double-down on your carbs then some buttered little potatoes or even mashed potatoes make a perfect side.
