Step-by-Step Instructions
- Prepare the Aromatic Base:
- Start by preheating your oven to three hundred fifty degrees. Melt the butter in a medium skillet over medium heat then add chopped onion and celery. Slowly cook for ten to fifteen minutes stirring often to coax out their natural sweetness without browning. Add garlic and thyme sauté until the garlic is fragrant about one minute.
- Blend the Savory Components:
- Take the skillet off the heat. Add Dijon mustard soy sauce tomato paste and Worcestershire mix well. Scrape the mixture into a bowl and set it aside to cool a bit.
- Bloom the Gelatin:
- In a large bowl lightly beat the eggs and stir in the milk. Evenly sprinkle the gelatin over the mixture and wait five minutes to hydrate every granule. This ensures your meatloaf will be moist and sliceable.
- Combine Meats and Mix-Ins:
- Add the beef pork ground Saltines and cooled aromatics to the egg mixture. Season generously with salt and black pepper. Use your hands or a spatula to gently mix until everything feels sticky but do not overwork the mixture.
- Prepare the Glaze:
- Stir ketchup and brown sugar together in a small bowl. This mixture will bring both sweetness and a glossy finish to the meatloaf.
- Assemble the Meatloaf:
- Spoon half of the meat mixture into a nine by five inch loaf pan pressing down to remove all air pockets. Spread half of the ketchup mixture on top. Repeat with the remaining meat mixture and finish with the rest of the glaze.
- Bake and Broil for Finish:
- Place in the oven and bake until an instant-read thermometer reads one hundred fifty five degrees in the center about forty to fifty minutes. To finish broil for two to three minutes until the top deepens in color and forms crisp caramelized edges.
- Rest and Serve:
- Allow the meatloaf to rest for fifteen minutes before unmolding and slicing. Drain off excess fat carefully before removing from the pan. Sprinkle with fresh thyme if using.

My favorite part is always the first slice when the ketchup glaze crackles under the knife. I still remember my dad’s face lighting up when I told him about the hidden gelatin trick and now it is a running family joke.
Storage Tips
Meatloaf keeps beautifully in the fridge for three days when wrapped well. For longer storage let it cool then wrap tightly and freeze for up to a month. When ready to reheat use a three hundred fifty degree oven and cover the loaf with foil to protect against dryness. Slices can also be microwaved for quick lunches.
Ingredient Substitutions
If you do not have ground pork simply swap in more ground beef or even ground turkey for a lighter flavor. Saltines can be substituted with panko or plain bread crumbs. For a dairy free version swap whole milk for an unsweetened plant-based alternative.
Serving Suggestions
For the coziest dinner serve slices of meatloaf with creamy mashed potatoes roasted baby carrots and buttered green beans. I also love it paired with a simple arugula salad to lighten things up or tucked in a sandwich with extra ketchup for lunch the next day.

A Bit of History
Meatloaf has humble roots in American kitchens dating back to the late eighteen hundreds when thrifty cooks would stretch proteins further by mixing them with bread grains and spices. Today it is still beloved for being affordable filling and easily customizable for any family palate.
