How to Make Marinated Zucchini and Red Onions

Follow these simple steps to prepare this delicious dish:

Step 1: Prepare Your Veggies

Start by washing your zucchini and red onions thoroughly under cold water. Slice them into even rounds—about half an inch thick—for consistent marinating.

Step 2: Mix the Marinade

In a large mixing bowl, whisk together olive oil, balsamic vinegar, minced garlic, salt, and pepper until well combined. This marinade is where all the magic begins!

Step 3: Combine Ingredients

Gently toss the sliced zucchini and red onions in the marinade mixture until every piece is coated evenly. Don’t be shy; use your hands if you want to ensure everything gets love!

Step 4: Marinate

Cover the bowl with plastic wrap or transfer everything into a resealable bag. Let it marinate in the refrigerator for at least 30 minutes—this allows those flavors to soak in and work their magic.

Step 5: Grill or Roast

Preheat your grill or oven (set at 400°F/200°C). If grilling, place vegetables directly on heated grates; if roasting, spread them out on a baking sheet lined with parchment paper. Cook until tender with slight char marks—about 10-15 minutes.

Step 6: Serve

Once cooked to perfection, transfer your marinated zucchini and red onions onto a serving platter. This colorful dish deserves to make an entrance!

Now that you’ve crafted this delightful side dish, watch as friends and family marvel at how something so simple can taste so spectacular. Enjoy every bite as you reminisce about your own kitchen adventures—and don’t forget to share your stories!
