These oven-baked tacos combine ground pork and chorizo with refried beans and melted Colby Jack cheese, all baked upright in hard shells until the cheese bubbles and the shells crisp up. The real reason to make them: one baking dish feeds the whole table at once, and the filling can be made a day ahead so dinner comes together fast when it counts.
Substitutions that actually work
- Pork chorizo: If you can’t find raw pork chorizo, use Mexican-spiced ground beef or add an extra half-teaspoon each of smoked paprika and garlic powder to plain ground pork. Cured Spanish chorizo is not a swap here — it won’t break down the same way in the skillet.
- Refried beans: Canned black beans mashed roughly with a fork work fine. The texture is slightly looser but still holds the filling together.
- Ketchup / tomato sauce: Either works. Tomato paste thinned with a splash of water is a good substitute if that’s what you have — use about half the volume.
- Colby Jack cheese: Monterey Jack melts just as well. Pre-shredded bags are convenient but block cheese you shred yourself melts more evenly and doesn’t clump.
- Canned green chilis: Diced fresh jalapeño (seeds removed for mild, seeds in for hot) is a direct swap. Start with one small jalapeño per can called for.
The short version of why this works
Two things make this recipe reliable. First, the refried beans aren’t just filler — they bind the ground pork and chorizo mixture so it stays put inside the shell instead of falling out the moment someone picks up a taco. Second, baking the shells upright and open-faced lets the cheese melt down into the filling rather than sitting on top of it, which means the shell, meat, and cheese fuse into a single unit that holds together through the whole meal. That structural integrity is what makes this practical for feeding a group — nobody’s chasing filling across their plate.
Mistakes to avoid
- Not draining the fat before adding beans and spices: Ground pork and chorizo together release a lot of fat. If you skip draining, the filling turns greasy and the shells go soggy in the oven. Tip the skillet and spoon off the excess before adding anything else.
- Overfilling the shells: It’s tempting to pack them, but overfilled shells crack or tip over in the dish. Fill to just below the rim so the cheese can seal the top without spilling over.
- Pulling them out before the cheese fully sets: The cheese needs to go from melted to lightly set so it acts as a lid. Give it the full bake time — pulling early means the filling is loose and the shells are still soft. Make sure the internal temperature of the pork filling reaches 160°F (71°C).
- Skipping the foil for the first half of baking: If your oven runs hot, the shell rims can over-brown before the filling heats through. Loosely tent the dish with foil for the first half, then remove it to finish and crisp the shells. Skip the garnish bar at the table — not worth the extra dishes when the tacos are already complete as-is.
- Storing leftovers in the shells: The shells soften overnight if stored assembled. If you know you’ll have leftovers, set aside some filling separately and reheat it to build fresh tacos the next day.
Special Oven-Baked Pork Tacos
Ingredients
- ¾ pound pork chorizo
1 teaspoon cumin
- 20 small hard taco shells
Instructions
- Heat about a tablespoon of extra virgin olive oil in a large skillet and add onion. Sweat for about 3 minutes. Add pork and chorizo and brown, breaking up with a wooden spoon. Cook until the meat is broken up into small bits and cooked through. Drain completely.
- Add the beans, tomato sauce, green chillies (add the whole can if you like more spice), and seasoning. Simmer until all is combined and thick, almost paste-like. Line a baking dish, or two, with the hard taco shells sitting upright.
- Bake the tacos at 400 degrees Fahrenheit for 10 to 20 minutes or until the cheese is melted.
- Serve with sour cream and a diced up tomato (with a few extra chilis and a little cilantro if you’re feeling ambitious).
- To reheat as leftovers: preheat the oven to 350 degrees and put tacos in while the oven is preheating. After about 5 minutes at full temp, crank the oven up to 400 degrees and bake for another 5 minutes or until the filling is heated through. Be sure to keep an eye on them, so the cheese doesn’t get overly brown.

FAQ
Can I make the filling ahead of time?
Yes — the filling keeps well in the fridge for up to two days. Let it cool completely before covering, then reheat it in a skillet over medium heat before assembling and baking so it’s hot going into the oven, which cuts bake time and ensures even heating.
How do I keep the taco shells from tipping over in the baking dish?
Pack them snugly side by side in the dish so they lean against each other — they hold each other upright. If your dish is too large and they have room to fall, fill the gaps with crumpled foil to prop them in place.
Can I double this recipe to feed a bigger group?
Easily. The filling scales up without any changes to technique — just use a larger skillet or cook it in two batches. You’ll need two baking dishes and may need to rotate them halfway through if your oven has hot spots.
How do I reheat leftover assembled tacos?
A hot oven at 375°F (190°C) for about 8–10 minutes brings them back close to fresh. Avoid the microwave — it steams the shells soft and you lose the crunch that makes these worth making.
Is there a way to make this less spicy for kids?
Use mild chorizo, skip or halve the red pepper flakes, and choose mild canned green chilis. The other spices — cumin, paprika, oregano — add flavor without heat, so the filling still tastes seasoned rather than bland.
What’s the best way to tell when the pork filling is fully cooked?
Ground pork must reach an internal temperature of 160°F (71°C) — use an instant-read thermometer to check the center of the filling in a shell before serving. Visually, there should be no pink remaining in the meat mixture.
