Mustard HP (Or A-1) Sauce Meatloaf: A Tangy Comfort Classic

Meatloaf. The word itself conjures up images of cozy family dinners, the savory aroma filling the kitchen, and that satisfying feeling of a hearty meal. For me, it’s always been tied to my grandmother’s kitchen. She had a knack for transforming simple ingredients into something truly special, and her meatloaf was legendary. Though she never shared her exact recipe, I remember the distinct tang of a secret ingredient that always kept me coming back for seconds. This recipe is my attempt to capture that magic, adding my own spin with the bold flavors of mustard and HP (or A-1) steak sauce.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 50 minutes
• Total Time: 1 hour 10 minutes
• Servings: 6-8
• Yield: 1 Meatloaf
• Dietary Type: Not specified

Ingredients

• 1 1⁄4 lbs ground beef
• 1 cup milk
• 1⁄3 cup Parmesan cheese or 1/3 cup Romano cheese (for a lower-carb option, use Parmesan or Romano instead of breadcrumbs)
• 1 teaspoon salt
• 1⁄4 teaspoon black pepper
• 1 tablespoon olive oil (or oil of preference)
• 1⁄2 cup chopped onion
• 1 egg
• 2 tablespoons mustard
• 2 tablespoons HP steak sauce (A-1 Sauce or Steaksauce of choice)
• 1⁄2 tablespoon Worcestershire sauce

Equipment Needed

• Large bowl
• Small bowl
• Small skillet
• 8″ x 8″ baking dish, 9″ round pan, or loaf pan
• Spatula

Instructions

1. Preheat your oven to 350°F (175°C). This ensures even cooking and prevents the meatloaf from drying out.
2. In a large bowl, gently crumble the 1 1⁄4 lbs of ground beef. Avoid overmixing at this stage, as it can lead to a tough meatloaf.
3. In a separate small bowl, combine the 1 cup milk, 1⁄3 cup Parmesan cheese or Romano cheese, 1 teaspoon salt, and 1⁄4 teaspoon black pepper. Allow this mixture to stand for 10 minutes. This allows the cheese to soften and the flavors to meld together, creating a more cohesive binder for the meatloaf.
4. Heat 1 tablespoon olive oil (or your preferred oil) in a small skillet over medium heat. Add 1⁄2 cup chopped onion and sauté until soft and lightly browned, about 5 minutes. Sautéing the onions first mellows their flavor and prevents them from being too harsh in the finished meatloaf.
5. Add the milk mixture, sautéed onions, 1 egg, 2 tablespoons mustard, 1⁄2 tablespoon Worcestershire sauce, and 1 tablespoon of HP steak sauce (or A-1) to the bowl with the ground beef.
6. Mix thoroughly but gently with your hands or a large spoon. Again, avoid overmixing. The goal is to combine all the ingredients evenly without compacting the meat.
7. Spoon the meatloaf mixture into a shallow 8″ x 8″ baking dish, a 9″ round pan, or a loaf pan. Smooth the top with a spatula. This will help the meatloaf cook evenly and create a visually appealing presentation.
8. Spread the remaining 1 tablespoon of HP steak sauce (or A-1) evenly over the top of the meatloaf. This creates a flavorful glaze that caramelizes during baking.
9. Bake at 350°F (175°C) until cooked through, about 50 minutes. To ensure the meatloaf is cooked through, insert a meat thermometer into the center. It should read 160°F (71°C).
10. Drain off any excess fat after baking. This will prevent the meatloaf from being greasy.
11. Allow the meatloaf to rest for at least 10 minutes before slicing and serving. This allows the juices to redistribute, resulting in a more tender and flavorful meatloaf.

Expert Tips & Tricks

• Don’t overmix! Overmixing the meatloaf mixture will result in a dense and tough meatloaf. Mix just until the ingredients are combined.
• Use lean ground beef. While a little fat is necessary for flavor, using lean ground beef (85/15 or 90/10) will help prevent the meatloaf from being too greasy.
• Add moisture. The milk and egg in this recipe help keep the meatloaf moist. You can also add other moist ingredients, such as grated zucchini or carrots, for added flavor and nutrients.
• Experiment with flavors. Feel free to customize this recipe to your liking. Add different herbs, spices, or sauces to create your own signature meatloaf.
• Make it ahead: The meatloaf can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. Just be sure to add a few extra minutes to the cooking time.

Serving & Storage Suggestions

Serve the meatloaf in wedges or 1/2″ slices. It pairs perfectly with a simple green salad, mashed potatoes, roasted vegetables, or even some extra mustard or steak sauce for dipping.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, you can freeze the meatloaf for up to 2-3 months. Thaw completely in the refrigerator before reheating.

To reheat, you can microwave the meatloaf in individual portions or bake it in the oven at 350°F (175°C) until heated through. Adding a little bit of broth or gravy can help keep it moist during reheating.
