Step-by-Step Preparation of French Onion Veggie Subs
Making French onion veggie subs is easier than you might think, and each step is simple yet rewarding. Here’s how you can whip up these delicious sandwiches in no time!
Sauté the onions
Start by warming up your cast iron skillet over medium-high heat. Add 2 tablespoons of butter and let it melt, infusing your kitchen with a fantastic aroma. Throw in 1 small diced onion and sauté it for about 5-7 minutes on medium-low heat. You want those onions to become wonderfully translucent. The key here is patience. As they soften, they’ll begin caramelizing, bringing out their natural sweetness. For a little extra sweetness, sprinkle in ½ tablespoon of brown sugar and mix. This step truly sets the tone for your French onion veggie subs.
Prepare the French onion dip
Once your onions are beautifully caramelized, it’s time to create that creamy dip. In a separate bowl, combine ½ cup of sour cream, ¼ cup of mayo, and the sautéed onion mixture. Add in 1 tablespoon of finely chopped chives, a teaspoon each of garlic powder and black pepper, and ½ tablespoon of soy sauce. Mix everything until completely blended. This dip is not only perfect for your subs but also great as an appetizer with some crunchy potato chips! You can serve it instantly or refrigerate it for an even richer flavor later.
Toast the sub roll
Now, let’s move on to the sub roll. Slice your large sub roll down the middle, and layer on your choice of sliced cheese—think melty goodness! Place it in your oven for just a couple of minutes or until the cheese begins to ooze. Toasting the bread adds a delightful crunch that perfectly complements the creamy dip and fresh veggies you’re about to add, creating a wonderful texture contrast.
Assemble the sub
Once your roll is perfectly toasted, it’s time to assemble your French onion veggie subs! Start by smearing a generous layer of your homemade French onion dip on the bottom half. Then, layer on fresh chopped lettuce, sliced tomatoes, cucumbers, and onions. Feel free to customize this part with your favorite veggies or add turkey bacon for that extra meaty bite! Cap it off with the other half of the roll, and your creation is almost ready to shine.
Serve and enjoy!
Slice your French onion veggie sub in half for easy handling and serve it up on a plate. Not only do these look appetizing, but they also pack a flavor punch! Gather some friends, grab a cozy drink, and dive into what just might become your new favorite sandwich. Happy munching!
