- 2 cloves garlic, minced (or 1 tsp garlic powder)
- 1 tsp dried oregano or fresh herbs (rosemary, thyme)

Equipment needed
A mixing bowl or jar for whisking the marinade is all you need. A blender or food processor can be used for a smooth texture but is not necessary.
Tips for choosing the best quality ingredients
Fresh herbs elevate the aroma and flavor more than dried. Extra virgin olive oil enhances richness and mouthfeelavoid refined oils for less flavor. Use freshly squeezed lemon juice or a good quality vinegar to brighten but not overpower.
Step-by-Step Instructions
Step 1 Prep vegetables: wash, peel, and chop into evenly sized pieces (about 1-inch chunks)
Stick to one-inch chunks for uniform roasting. No need to peel tender skins if cleancarrots and sweet potatoes are great examples. This ensures even cooking and caramelization.
Step 2 Mix the marinade: whisk all ingredients in a bowl for 1 minute until emulsified
Whisk olive oil, vinegar or lemon juice, garlic, herbs, mustard, salt, pepper, and optional sweetener until fully combined. Emulsifying helps the marinade coat evenly and cling well during roasting.
Step 3 Toss vegetables in marinade ensuring full coating; let sit 10-15 minutes at room temperature
Allowing vegetables to rest in the marinade for 1015 minutes helps flavors soak in. Avoid marinating porous veggies like zucchini longer than 20 minutes to prevent sogginess. Stir occasionally for even coverage.
Step 4 Roast at 425F (220C) for 2530 minutes, turning halfway; serve warm or store
Spread vegetables on a baking sheet in one layer. Roast at 425F for 25 to 30 minutes until edges are crisp and golden brown. Halfway through, turn them to ensure even browning. Serve immediately or cool and refrigerate.

Pro Tips & Troubleshooting

Always give your marinade a good whisk before use to blend oil and acid well, ensuring even coating on the vegetables.
Why flavor or color might be off and how to fix it
