01Rinse and cut the tripe.
Rinse the pre-cooked tripe under cold water, drain thoroughly and cut it into even strips.
The pieces should be clean-smelling, drained and similar in width.
Roman tripe is simmered in a tomato-rich soffritto with guanciale, then finished with Pecorino Romano and fresh Roman mint for the classic Saturday-trattoria profile.

Turismo Roma identifies trippa alla romana as a historic capitoline dish traditionally associated with Saturday lunch and the city’s quinto quarto culture.
The defining finishing ingredients are Pecorino Romano and Roman mint, added after a long tomato braise rather than cooked away at the start.
Using good-quality pre-cooked tripe keeps the home method manageable while preserving the required tender-but-slightly-resilient texture.
The finished sauce should remain abundant enough to coat the tripe and invite bread, not reduce to a dry ragù.
Rinse the pre-cooked tripe under cold water, drain thoroughly and cut it into even strips.
The pieces should be clean-smelling, drained and similar in width.
Warm the casserole over medium-low heat and cook guanciale with the olive oil for 4–5 minutes.
The fat should turn translucent and lightly render without scorching.
Add onion, carrot, celery and garlic and cook 8–10 minutes, stirring often.
Vegetables should be soft and aromatic with only light colour.
Add tripe, salt and pepper and cook 5 minutes so the strips absorb the soffritto.
The tripe should look glossy and evenly coated.
Stir in crushed tomatoes and 150 ml hot stock; bring to a gentle simmer.
The tripe should sit in a loose, red sauce rather than a dry pan.
Cover partially and simmer 55–65 minutes, stirring and adding more hot liquid as needed.
Tripe should be tender but retain slight bite; sauce should be abundant and cohesive.
Uncover for the final 10 minutes if the sauce is too loose, or add stock if it tightens too far.
Sauce should cling to strips while leaving a spoonable pool in the pan.
Remove from heat and let stand 5 minutes.
The bubbling should subside while the sauce remains very hot.
Serve in warm bowls with Pecorino Romano and chopped mint over each portion.
The cheese should begin melting on contact and the mint should smell fresh, not cooked out.
Serve with crusty bread; extra Pecorino can be offered at the table.
The braised tripe can be made a day ahead; reheat gently and add mint and cheese only at service.
If using very soft pre-cooked tripe, reduce the braise slightly rather than cooking it to mush.
Approximate; sodium varies strongly with guanciale, tripe and Pecorino.
Buy tripe from a reputable supplier and keep refrigerated.
Reheat cooked tripe dishes to at least 74°C before serving leftovers.
Cool leftovers within 2 hours and refrigerate up to 3 days.

Yes; good-quality pre-cooked tripe is practical for home cooking and still benefits from a long sauce braise.
No. The traditional service keeps enough tomato sauce around the tripe to remain succulent.
