In a large mixing bowl, combine the baby potatoes, carrots, bell peppers, zucchini, and cherry tomatoes.
In a separate bowl, whisk together the melted butter, minced garlic, dried Italian herbs, red pepper flakes (if using), salt, and pepper until well combined.
Pour the herb butter over the vegetables and toss gently until all the vegetables are well coated.
Line a large baking sheet with parchment paper, then spread the coated vegetables in a single layer to ensure even roasting.
Roast in the preheated oven for 25-30 minutes, stirring halfway through, until the vegetables are tender and golden brown.
Once out of the oven, sprinkle freshly chopped parsley over the top for a burst of freshness. Serve warm as a delightful side dish.
Notes
Optional red pepper flakes can be adjusted based on heat preference.
