Servings 3 Sandwiches

Ingredients

For the Green Goddess Sauce

  • ½ cup mayonnaise
  • ¼ cup sour cream or Greek yogurt
  • 1-2 cloves garlic
  • 2 anchovy fillets optional
  • 1 tbsp lemon juice
  • 1 tbsp extra virgin olive oil
  • salt and pepper to taste

For the Sandwich

  • 1 sourdough baguette cut into thirds
  • 6-8 oz fresh mozzarella sliced
  • 1-2 ripe tomatoes sliced
  • ¼ cup parmesan cheese freshly grated
  • 1 handful fresh arugula
  • ¼ cup sliced sweet red peppers* drained
  • drizzle of red wine vinegar, lemon juice, or extra virgin olive oil optional, for brightness
  • butter or olive oil for toasting

Instructions

  • Blend all sauce ingredients until smooth and creamy with small flecks of herbs. Taste and adjust seasoning as needed.

    • A little extra garlic gives that subtle “aioli” flavor similar to the Panera version.
  • Lightly salt the tomato slices and let sit for 5–10 minutes, then pat dry.

    • Skipping this step can make the sandwich soggy.
  • Slice the baguette evenly into thirds. Lightly toast the cut sides in a skillet with some butter until just crisp.

  • Spread green goddess sauce on both sides of the bread. I like to add mozzarella slices directly onto both halves first, which helps create an extra melty layer and keeps the fillings tucked in nicely. Then layer the tomatoes, peppers, and sprinkle with parmesan cheese.

  • Heat a skillet over medium-low heat and add butter or oil. Place the sandwich in the pan and cook until deeply golden and crisp, then flip and continue cooking until the cheese is fully melted. I like to cover the skillet with a lid for a minute or two to help the mozzarella melt evenly without over-browning the bread.

Notes

Optional Oven Method (Easy Alternative)

Preheat oven to 375°F. Assemble the sandwich and place on a baking sheet.
Bake for 8–10 minutes until heated through and cheese is melted.
Note: the skillet method gives the crispiest, most Panera-style result.

Other Notes

Use a sturdy loaf like sourdough, ciabatta, or focaccia for the best crispy texture and structure. Softer sandwich bread tends to flatten and steam.
Cooking the sandwich over medium-low heat gives the cheese enough time to melt fully before the bread gets too dark.
Covering the skillet with a lid for 1–2 minutes helps the mozzarella melt evenly while keeping the bread golden and crisp.
Add the arugula right before serving so it stays fresh and peppery instead of wilting into the hot sandwich.
This sandwich is best enjoyed fresh and hot, but leftover green goddess sauce can be stored in an airtight container in the fridge for up to 3 days.
