Let the short ribs come to room temperature about 30 minutes before cooking
Preheat your oven to 325 degreesĀ
Pat the short ribs dry with paper towels, season generously with salt and black pepper and press all sides in all purpose flour
Place a braiser or dutch oven oven medium to medium high heat and add 2 tablespoons of butter and olive oil
Once the braiser is warm, sear the short ribs on all sides (work in batches to avoid crowding the pot), transfer onto a plate and set them aside for now
Add the chopped yellow onion, carrots and celery and cook for about 5 minutes or until beginning to soften
Add 6 cloves of finely minced garlic and 3 tablespoons of tomato paste and stir until evenly distributed
Add 2 cups of beef broth and 2 cups of a dry red wine and bring to a simmer
Transfer the seared short ribs back into the braiser along with 3 sprigs of rosemary, 10 sprigs of thyme and 3 bay leaves (or a teaspoon of dried herbs)
Cover the braiser and transfer into a 325 degree oven
Bake for about 3 hours or until very tender (see additional cooking options above)
Once the short ribs are tender, remove the herbs and transfer the short ribs onto a plate
Place the pot back over medium high heat and bring the sauce to a simmer
To finish the gravy, either strain the gravy to remove the vegetables and leftover herbs or use an immersion blender to blend smooth and then simmer uncovered until thickened
Serve over mashed potatoes
