Easy Instant Pot Tomato Pork Roast

Lunch, Red Meat

March 29, 2026

There’s something incredibly comforting about a perfectly cooked pork roast, and this recipe delivers all that cozy goodness with a modern, time-saving twist. By starting in the Instant Pot, we lock in moisture and flavor, creating fall-apart tender meat in just 20 minutes. A quick finish in the oven with fresh tomatoes, onions, and cauliflower brings everything together, charring the edges beautifully and creating a complete, one-pan meal. It’s a rustic, satisfying dish that tastes like it’s been slow-cooking all day, but it’ll be on your table in under an hour!

Ingredients

• 2 lbs (900g) pork butt, sliced
• 2 cups (200g) cauliflower, chopped into florets
• 2 large tomatoes, sliced
• 2 large onions, sliced
• 4 tbsp (60ml) olive oil
• 3 tbsp (42g) butter
• 4 cups (960ml) beef broth
• Spices
• 1 ½ tsp salt
• 1 tsp freshly ground black pepper
• ½ tsp nutmeg

Instructions

1. Directions
2. In a bowl, rub the sliced pork with olive oil, then season generously with salt, pepper, and nutmeg.
3. Place the seasoned pork into the inner pot of your Instant Pot and pour in the beef broth.
4. Secure the lid and set the steam release handle to the ‘Sealing’ position. Select the ‘Manual’ or ‘Pressure Cook’ button and set the timer for 20 minutes on high pressure.
5. While the pork is cooking, preheat your oven to 400°F (200°C). Generously brush a large baking pan with butter and set it aside.
6. When the Instant Pot cycle is complete, carefully perform a quick pressure release. Once the pin drops, open the lid.
7. Using tongs, transfer the tender pork to your prepared baking pan. Arrange the cauliflower florets, sliced onions, and sliced tomatoes around the meat.
8. Ladle about one cup of the hot broth from the Instant Pot over the pork and vegetables.
9. Roast in the preheated oven for 15-20 minutes, or until the vegetables are fork-tender and the pork is lightly charred and browned on the edges. Serve immediately.

Pro Tips

• For a deeper, richer flavor, use the ‘Sauté’ function on your Instant Pot to sear the seasoned pork on all sides in olive oil before adding the broth and pressure cooking.
• Don’t discard the leftover broth! Simmer it on the ‘Sauté’ function and thicken with a cornstarch slurry to create a delicious gravy to serve alongside the roast.
• Add a few cloves of whole garlic or a sprig of fresh rosemary to the Instant Pot with the broth for an extra layer of aromatic flavor.
• For a crispier finish, switch the oven to the broil setting for the last 2-3 minutes of cooking, watching carefully to prevent burning.
