Measure and mix marinade together, pour over steaks in a shallow dish and evenly coat both sides. Save extra marinade for later use.
Wash and cut potatoes and carrots to size. Add to a large bowl and toss with stock, seasonings to taste and fresh thyme. Alternatively you can make everything lemon pepper tasting if that is what you're into it.
Line a baking sheet with parchment paper and spread everything into a single layer.
Bake for 30 minutes. Remove from the oven and flip everything. Use extra marinade to baste cauliflower steaks liberally.
Add in your pearl onions and bake for another 15-20 minutes, or until potatoes are tender.
Top steaks with remaining marinade and serve hot with salt and pepper to taste.
Garnish with diced green onion for more flavor, optional.
Not a fan of lemon pepper? Use your favorite marinade! Save extra cauliflower to make wings or fried "rice".
