Slow Cooker Lasagna

Set it and forget it — this lasagna builds layers of flavor while you go about your day.

Amount	Ingredient
1 lb	90% lean ground beef (or ground bison)
1/2	Medium onion, diced
3 cloves	Garlic, minced
1 tsp	Kosher salt (divided)
1 tsp	Italian seasoning
2 (28-oz) cans	Crushed tomatoes
1 (15-oz) container	Whole-milk ricotta cheese
1	Large egg
1/2 cup	Grated Parmigiano-Reggiano
3 cups	Shredded low-moisture mozzarella
12	No-boil lasagna noodles
Fresh basil	For garnish

🥘 Equipment

• Large skillet
• 6-qt or larger slow cooker
• Medium bowl
• Spatula

📋 Preparation

Step 1: Brown the Meat

Spray a large skillet with olive oil and set over medium-high heat. Add the ground beef and 3/4 teaspoon salt. Cook, breaking the meat apart, until mostly browned — about 3-4 minutes.

Add the onion, garlic, remaining salt, and Italian seasoning. Continue cooking until the onion softens, about 3 minutes more.

Step 2: Build the Sauce

Stir in both cans of crushed tomatoes. Bring to a simmer, then remove from heat. This is your lasagna sauce — it will finish cooking in the slow cooker.

Step 3: Make the Ricotta Layer

In a medium bowl, combine the ricotta, egg, and half the grated Parmigiano. Stir until smooth. Set aside.

Step 4: Layer in the Slow Cooker

Spread a thin layer of sauce (about 1 cup) on the bottom of the slow cooker.

Layer in this order, repeating 3 times:

1. No-boil lasagna noodles — break to fit as needed
2. Ricotta mixture — spread evenly (about 1/3 cup per layer)
3. Shredded mozzarella — generous handful
4. Meat sauce — enough to cover

Finish with a final layer of noodles, remaining sauce, and all remaining mozzarella and Parmigiano on top.

Step 5: Cook

Cover and cook on Low for 4-6 hours or High for 2-3 hours. The lasagna is done when the noodles are tender and the edges are bubbling.

Pro tip: If the top looks pale after cooking, switch to Warm and let it rest 20 minutes — the carryover heat firms up the layers for cleaner slices.

Step 6: Rest & Serve

Turn off the slow cooker and let the lasagna rest, uncovered, for 15-20 minutes before slicing. This is essential — it prevents the dreaded "lasagna landslide" on the plate.

Garnish with fresh basil.

🧑‍🍳 Chef's Tips

• No-boil noodles are key: Regular lasagna noodles need parboiling, which adds 30 minutes and makes them harder to layer. No-boil noodles absorb moisture from the sauce as they cook, perfectly.
• Don't overdo the sauce: Slow cookers trap steam. Too much liquid = soupy lasagna. Trust the measurements above.
• Lean meat matters: 90% lean or higher prevents a greasy final dish. If using 80%, drain the fat after browning.
• Let it rest: The most common mistake is cutting too soon. 15-20 minutes of rest transforms a wobbly mess into perfect slices.

❄️ Storage

Method	Details
Fridge	Cover and refrigerate up to 4 days. Reheat individual portions in the microwave (90 sec) or covered in a 350°F oven (15 min).
Freezer	Assemble completely in a freezer-safe container but do not cook. Freeze up to 3 months. Thaw overnight in the fridge, then cook on Low for 5-6 hours.

🍷 Wine Pairing

• Chianti Classico — high acidity cuts through the meat and cheese
• Sangiovese — cherry and herb notes complement the Italian seasoning
• Zinfandel — jammy fruit stands up to the hearty sauce
