This stew is the ultimate fall or winter comfort food! It takes a little longer to prepare than our usual dinner recipes, so we recommend making it ahead if needed. If you have the time, simmer it an extra hour to make the beef extra tender. If you like a thicker stew, you can add a cornstarch slurry at the end by combining 2-3 teaspoons cornstarch with a little bit of water, pour into the stew, and bring to a simmer for at least 2 minutes.
