Lay beef cutlets flat and pound to a uniform 1/4-inch thickness using a meat mallet.
Season the surface of the beef evenly with salt and black pepper.
Distribute minced garlic, breadcrumbs, and Parmesan cheese over the beef, leaving a 1/2-inch border at the edges.
Layer fresh spinach leaves and Provolone cheese slices over the breadcrumb mixture.
Roll the beef cutlets tightly and secure each roll with kitchen twine.
Heat olive oil in a heavy-bottomed skillet or Dutch oven over medium-high heat.
Sear the beef rolls until browned on all sides, approximately 8 to 10 minutes total.
Deglaze the skillet with red wine, scraping up any browned bits from the bottom.
Add the marinara sauce, reduce heat to low, cover, and simmer for 90 minutes until the beef is fork-tender.
Remove kitchen twine and slice the rolls into 1-inch thick rounds to serve.
