This Instant Pot version keeps that slow-braised soul by layering the classic steps — rendered pancetta, an ultra-fine soffritto, browned beef and pork, wine reduction, and the almost-counterintuitive addition of milk — then squeezes them into a 75–90 minute workflow that yields deep, concentrated flavor with minimal babysitting. The texture should be spoonable: shredded meat suspended in a glossy, slightly thickened tomato sauce that clings to broad noodles rather than running off them. Small dice on the vegetables and properly rendered pancetta are the unsung keys to sweetness and mouthfeel here. It’s a recipe for anyone who craves restaurant-style richness but can’t commit an entire afternoon to simmering a pot. Hands-on time is concentrated at the start — sweat, brown, deglaze — and the pressure cooker does the slow work, producing a clarified beefy depth that sings when finished with freshly grated Parmigiano and an extra drizzle of olive oil. Make a double batch for easy weeknight dinners, or portion and freeze — the flavors only deepen over time. ## Recipe Information - Prep Time: 20 minutes - Cook Time: 90 minutes - Total Time: 110 minutes - Servings: 4 - Difficulty: Medium - Category: Instant Pot ## Ingredients ### Render pancetta and sweat the soffritto - 2 tbsp Extra-virgin olive oil - 4 oz Pancetta, diced - 1 1/2 cups Aromatic soffritto (onion, carrot, celery), finely diced ### Brown the ground meats - 1 lb Ground beef (80/20) - 1/2 lb Ground pork ### Deglaze with wine and concentrate flavors - 1 cup Dry red wine - 2 tbsp Tomato paste ### Add milk to soften acidity - 1 cup Whole milk ### Add tomatoes and pressure-cook - 28 oz Crushed tomatoes (canned) - 1 cup Low-sodium beef broth ## Instructions ### 1. Render pancetta and sweat the soffritto Set the Instant Pot to Sauté (normal) and heat the olive oil. Add diced pancetta and cook until the fat renders and pieces are golden, then add the finely diced onion, carrot and celery and cook gently until softened and translucent, about 6–8 minutes. Stir frequently to avoid browning the vegetables too quickly so they become sweet and aromatic. ### 2. Brown the ground meats Add the ground beef and ground pork to the pot, breaking them up with a spoon. Cook, stirring and scraping, until no pink remains and the meat begins to brown and develop fond on the bottom, about 6–8 minutes. Season lightly with salt and black pepper as you brown to help concentrate flavor. ### 3. Deglaze with wine and concentrate flavors Pour in the red wine to deglaze, scraping up browned bits from the bottom of the pot, and let the wine reduce by about half, roughly 3–5 minutes. Stir in the tomato paste and cook for 1–2 minutes to caramelize and deepen the paste’s flavor; this step builds the backbone of the ragu. ### 4. Add milk to soften acidity Pour in the whole milk and simmer briefly for 3–4 minutes to let it reduce slightly and mellow the tomatoes’ acidity. This classic Bolognese step yields a rounder, silkier sauce and removes any raw-cooked dairy taste before pressure cooking. ### 5. Add tomatoes and pressure-cook Stir in the crushed tomatoes and beef broth, scrape the pot one more time, then lock the lid and set the Instant Pot to High Pressure for 60 minutes. When the cook cycle completes, allow a natural pressure release for 15–20 minutes, then quick-release any remaining pressure and open the lid cautiously. ### 6. Reduce, season, and finish If the ragu is too thin, set the Instant Pot to Sauté and simmer uncovered for 5–10 minutes to reduce to your desired consistency, stirring frequently. Taste and adjust seasoning with salt and pepper, shred larger meat pieces with a spoon if desired, and serve over fresh pasta with grated Parmesan or store cooled in the fridge for up to 4 days or freeze for longer. ## Nutrition Estimated nutrition per serving (about 1¼ cups): - Calories: 875 kcal - Protein: 44.7 g - Carbohydrates: 34.7 g - Fat: 54.8 g - Saturated Fat: 20.7 g - Trans Fat: 1.1 g - Fiber: 4.9 g - Sugar: 11.3 g - Added Sugars: 0 g - Cholesterol: 162 mg - Sodium: 1240 mg - Potassium: 1443 mg - Calcium: 244 mg - Iron: 6.3 mg - Vitamin D: 0 mcg ## Tips ### Dice soffritto finely Cut the onion, carrot and celery into very small, uniform pieces so they almost melt into the sauce and provide sweetness without texture that competes with the meat. ### Render pancetta thoroughly Cook the pancetta until its fat is clear and the pieces are golden; that fat carries flavor and helps to coat the meat and vegetables for a silkier finish. ### Develop a good fond Brown the meat until you see dark bits on the pot surface, then deglaze with wine to lift those concentrated flavors into the sauce. ### Add milk first Pouring in milk before the tomatoes tempers acidity and promotes a round, creamy mouthfeel; simmer it briefly so it reduces and loses any raw dairy taste. ### Finish by reducing If the pressure-cooked ragu seems loose, use Sauté to reduce uncovered in short bursts, stirring to prevent scorching and to concentrate flavors. ## Variations and Substitutions ### Pork-and-beef swap Use 1.5 lb ground beef (80/20) in place of the pork for a beefier profile, or add 6 oz ground veal for a more classical, tender texture. ### Pancetta-free option Replace pancetta with 2 tbsp olive oil plus a couple teaspoons of smoked paprika for a savory, non-cured alternative that still builds depth. ### Mushroom-lentil Bolognese For a vegetarian version, swap the meats for a mix of finely chopped cremini mushrooms and brown lentils, and use vegetable broth in place of beef stock. ### White wine & herb twist Substitute the red wine with dry white wine and add a sprig of thyme and bay leaf for a brighter, herb-forward variation that pairs well with pasta stuffed or thin. ## Notes ### Storage and Make-Ahead Cool the ragu quickly and store in airtight containers in the refrigerator for up to 4 days or freeze in portions for up to 3 months. For best texture, thaw overnight in the fridge before reheating. Reheat gently in a saucepan over low heat with a splash of broth or milk to loosen the sauce and bring back silkiness, stirring occasionally to prevent sticking. ### Serving Suggestions Serve this ragu with wide pasta like tagliatelle, pappardelle or rigatoni so the sauce clings to each bite; finish with a generous grating of Parmigiano-Reggiano and a drizzle of extra-virgin olive oil. Pair with a simple peppery arugula salad dressed with lemon and olive oil and a medium-bodied red like Sangiovese or Chianti to cut the richness. ## Frequently Asked Questions ### Can I shorten the pressure-cook time? You can reduce the pressure time to 45 minutes for a quicker meal, but 60 minutes develops deeper collagen breakdown and a richer mouthfeel; a shorter time may yield a less tender texture. ### Why do you add milk before the tomatoes? Milk mellows tomato acidity and rounds out the sauce, while also helping to tenderize the meat proteins during braising for a silkier finish. ### My sauce is too thin—how do I thicken it? Use the Instant Pot's Sauté function and simmer uncovered for 5–15 minutes to reduce, stirring frequently; for a slightly thicker texture without reducing too long, whisk in a small knob of butter at the end for gloss and body. ### Can I brown the meat separately? Yes—browning in batches in a skillet develops more crust and prevents steaming; deglaze the skillet with wine and add those juices back into the Instant Pot to preserve flavor. ### Is this recipe freezer-friendly? Absolutely—portion into meal-sized containers and freeze for up to 3 months; thaw overnight and reheat gently on the stovetop, adding a splash of broth or milk to refresh the sauce. ## Related Recipes and Guides - [Instant Pot Strawberry Jam](https://www.topshelf.recipes/recipes/instant-pot-strawberry-jam) - [Instant Pot Swedish Meatballs in Creamy Gravy](https://www.topshelf.recipes/recipes/instant-pot-swedish-meatballs-creamy-gravy) - [Snake River Farms Beef Tallow Instant Pot Braised Short Ribs](https://www.topshelf.recipes/recipes/snake-river-farms-beef-tallow-instant-pot-braised-short-ribs) - [Instant Pot Beef Stew — Tender Chuck in 45 Minutes](https://www.topshelf.recipes/recipes/instant-pot-beef-stew-tender-chuck-45-min) - [Instant Pot Red Lentil Dal](https://www.topshelf.recipes/recipes/instant-pot-red-lentil-dal-coconut-turmeric) - [Instant Pot Top Round Roast for Tender Sliced Roast Beef](https://www.topshelf.recipes/recipes/instant-pot-top-round-roast-tender-sliced-roast-beef) - [Ultra-Tender Pork Spare Ribs: Tips & Techniques for Fall-Off-the-Bone Success](https://www.topshelf.recipes/articles/ultra-tender-pork-spare-ribs-tips-techniques) - [The Year's Most Popular Seasonal Recipes: 12 Crowd-Pleasing Dishes (One for Each Month) with Grilling & Campfire Twists](https://www.topshelf.recipes/articles/most-popular-seasonal-recipes-12-crowd-pleasers-grill-campfire-twists) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan)
