Ingredients
The foundation of these squares is a light, buttery biscuit dough that provides a tender crumb while holding up to hearty fillings. Italian cured meats supply salty depth, provolone adds melt‑in‑your‑mouth richness, and fresh vegetables contribute crunch and brightness. The finishing herb‑garlic oil ties everything together with a fragrant, glossy sheen.
Biscuit Base
- 2 cups all‑purpose flour
- 1 tablespoon baking powder
- ½ teaspoon salt
- ¼ cup cold unsalted butter, cubed
- ¾ cup whole milk
Filling
- ½ cup thinly sliced Genoa salami
- ½ cup thinly sliced pepperoni
- ½ cup thinly sliced mortadella
- 1 cup shredded provolone cheese
- ½ cup diced red bell pepper
- ¼ cup thinly sliced red onion
- ¼ cup sliced black olives (optional)
Herb‑Garlic Oil
- ¼ cup extra‑virgin olive oil
- 2 cloves garlic, minced
- 1 tablespoon chopped fresh basil
- 1 teaspoon red‑wine vinegar
- Salt and freshly ground black pepper to taste
These ingredients work together to create a balanced bite. The biscuit base offers a tender, slightly sweet canvas that absorbs the herb‑garlic oil without becoming soggy. The cured meats contribute salty, umami depth, while provolone melts into a creamy layer that unifies the toppings. Fresh vegetables add crunch and a pop of color, and the oil finishes the dish with a bright, aromatic sheen that mimics the classic sub drizzle.
Step-by-Step Instructions
Preparing the Biscuit Dough
In a large mixing bowl combine 2 cups all‑purpose flour, 1 tablespoon baking powder, and ½ teaspoon salt. Cut the cold butter into the dry ingredients using a pastry cutter or fingertips until the mixture resembles coarse crumbs. Create a well in the center and pour in ¾ cup whole milk, stirring gently until a soft dough forms. Avoid over‑mixing, which can toughen the biscuits.
Assembling the Squares
- Roll and Cut. Lightly flour a surface and roll the dough to a ½‑inch thickness. Using a 3‑inch square cutter, cut out 8 squares and place them on a parchment‑lined baking sheet, leaving a little space between each.
- Layer the Meats. Evenly distribute the sliced salami, pepperoni, and mortadella over each biscuit square, ensuring a thin, even layer that will melt into the dough as it bakes.
- Add Veggies & Cheese. Sprinkle the diced red bell pepper, red onion, and olives (if using) over the meats. Top each square with a generous handful of shredded provolone, which will melt into a golden blanket.
- Bake. Preheat the oven to 375°F (190°C). Bake the assembled squares for 15‑18 minutes, or until the biscuits are puffed and golden and the cheese is bubbly and lightly browned.
Finishing with Herb‑Garlic Oil
While the squares bake, whisk together ¼ cup extra‑virgin olive oil, 2 cloves minced garlic, 1 tablespoon chopped fresh basil, and 1 teaspoon red‑wine vinegar. Season with salt and pepper. As soon as the squares exit the oven, drizzle the warm oil over each one, allowing it to seep into the biscuit and coat the toppings. This final step adds shine, flavor, and that unmistakable Italian sub tang.
Tips & Tricks
Perfecting the Recipe
Cold Butter Is Key: Keep the butter chilled until it hits the flour. Cold pockets melt during baking, creating flaky layers.
Don’t Over‑Mix: Mix just until the dough comes together. Over‑working develops gluten, leading to a tough biscuit.
Even Thickness: Roll the dough to a uniform ½‑inch thickness so all squares bake evenly.
Pre‑heat the Oven: A fully heated oven ensures an immediate rise and a golden crust.
Flavor Enhancements
Add a splash of fresh lemon juice to the herb‑garlic oil for extra brightness. Toss a pinch of red‑pepper flakes into the oil if you enjoy a gentle heat. For richer depth, stir in a teaspoon of grated Parmesan just before drizzling.
Common Mistakes to Avoid
Resist the urge to stack the toppings too high; excess moisture can sog the biscuit. Also, avoid using pre‑cooked meats that are overly salty—taste as you go and adjust seasoning accordingly.
Pro Tips
Use a Light Hand with Oil: Drizzle just enough to coat; too much can make the squares greasy.
Finish Under the Broiler: For an extra golden top, broil for 1‑2 minutes after baking, watching closely.
Season the Biscuit Base: Add a pinch of Italian seasoning to the dough for subtle herb notes throughout.
Serve Warm: These squares are at their best within 15 minutes of leaving the oven; reheating can diminish the flaky texture.
Variations
Ingredient Swaps
Swap the trio of salami, pepperoni, and mortadella for sliced prosciutto, capicola, or even grilled chicken for a leaner option. Replace provolone with mozzarella or Fontina for a milder melt. For a vegetarian spin, use roasted red peppers, artichoke hearts, and smoked mozzarella.
Dietary Adjustments
Use a gluten‑free flour blend and gluten‑free baking powder for a celiac‑friendly version. Substitute the butter with a plant‑based alternative and choose dairy‑free cheese to keep it vegan. For low‑carb, replace the biscuit with almond‑flour dough and skip the sugar in the oil drizzle.
Serving Suggestions
Pair the squares with a simple arugula salad tossed in lemon vinaigrette, or serve alongside a bowl of minestrone for a heartier brunch. A side of roasted potatoes or a light fruit salad balances the savory richness and adds color to the plate.
Storage Info
Leftover Storage
Allow any leftovers to cool completely, then place the squares in an airtight container. Refrigerate for up to 3 days. For longer keeping, wrap each square tightly in plastic wrap, then foil, and freeze for up to 2 months. Proper sealing prevents freezer burn and maintains the biscuit’s texture.
Reheating Instructions
Reheat in a pre‑heated 350°F oven for 10‑12 minutes, covered with foil to keep moisture in. For a crispier top, uncover for the final 2 minutes. If you’re short on time, microwave a single square on 50% power for 45 seconds, then finish under a hot skillet for 1 minute to restore a slight crunch.
