Preheat your oven to 400°F.
In a large oven-safe skillet, heat the olive oil over medium-high heat and brown the ground beef until no longer pink.
Add the carrots, yellow onion, and cremini mushrooms to the skillet, sautéing for 6 minutes until the vegetables are tender.
Sprinkle the arrowroot starch over the beef and vegetables, stirring constantly for 1 minute to coat everything evenly.
Pour in the beef bone broth and add the frozen peas, sea salt, black pepper, dried thyme, and dried rosemary.
Simmer the mixture for 3 minutes until the sauce thickens into a glossy, savory gravy.
In a small bowl, whisk together the almond flour and extra virgin olive oil until a crumbly topping forms.
Sprinkle the almond mixture over the skillet and bake for 10-12 minutes until the herb crust is golden and toasted.
