Instant Pot Duo 7-in-1 Review: 5 Months of Keto Batch Cooking

Why the Instant Pot Is a Keto Kitchen Workhorse

When I started keto meal prep, I had a routine: every Sunday, I’d spend 4-5 hours cooking proteins and sides for the week. The Instant Pot Duo 7-in-1 cut that down to 90 minutes. Not because it’s magic — because pressure cooking is fundamentally faster than any other wet-heat cooking method, and keto meal prep is heavily protein-and-broth based, which is exactly what pressure cookers excel at.

I used the 6-quart Duo 7-in-1 for 5 months of weekly batch cooking. Here’s what I learned.

Bone Broth: The Main Reason Keto Dieters Need This

Before the Instant Pot, I made bone broth on the stovetop. It took 24 hours of simmering, required monitoring, made the whole house smell like beef for a day, and the results were inconsistent — sometimes it gelled, sometimes it didn’t.

The Instant Pot changed bone broth from a weekend project to a weeknight afterthought:

Beef bone broth recipe (tested 12 times):

• 3 pounds beef marrow/soup bones
• 1 onion, 2 carrots, 2 celery stalks
• 2 tbsp apple cider vinegar
• Water to max line
• 90 minutes high pressure, 10 minutes natural release

Results: Every single batch gelled firmly when chilled. The 90-minute pressure cook extracts more collagen than 12 hours of stovetop simmering — I confirmed this by comparing the gel firmness side by side. The broth is rich, deeply flavored, and consistently good.

Chicken bone broth (tested 8 times):

• 2 chicken carcasses (from Costco rotisserie chickens)
• Same aromatics
• 60 minutes high pressure, natural release

Results: Perfect gel every time. The pressure extraction pulls collagen from chicken bones faster and more completely than stovetop. I make this every week now — eat the rotisserie chicken, throw the bones in the Instant Pot, have broth for the week.

The Instant Pot paid for itself in bone broth alone. At $6/quart for quality bone broth at the store, and I make 2-3 quarts per week, that’s $12-18/week saved. The $129 Instant Pot pays for itself in 8-10 weeks just from broth.

Pulled Pork: 45 Minutes vs. 6 Hours

Keto pulled pork is a staple — fatty, flavorful, and makes 10+ meals from one cut of meat. Here’s my weekly recipe:

• 3-pound pork shoulder (Boston butt)
• 1 cup water or broth
• Keto BBQ rub (salt, pepper, smoked paprika, garlic powder)
• 45 minutes high pressure, 15 minutes natural release

Result: Fork-tender pulled pork that shreds with two forks. The fat renders into the cooking liquid, which I save and use for cooking greens or scrambling eggs. 3 pounds yields about 8-10 servings at ~30g protein and ~20g fat each.

On the stovetop or slow cooker, this same recipe takes 6 hours. The Instant Pot doesn’t just save time — the pressure forces the seasoning deeper into the meat, producing more flavorful results than slow cooking in my experience.

I also tested the “crispy edges” technique: after shredding, spread the pork on a sheet pan and broil for 5 minutes. The Instant Pot’s tender shred + broiler crisp edges = keto carnitas that rival any restaurant.

Beef Short Ribs: 50 Minutes vs. 3 Hours

Beef short ribs are a keto superfood — extremely fatty, deeply flavorful, and packed with collagen. They’re also expensive ($10-15/lb), so ruining them is costly.

Stovetop method (previous): Sear, braise in red wine and broth, 3 hours at 325°F. Results were good but the meat could be inconsistent — sometimes fall-off-the-bone, sometimes tough.

Instant Pot method (tested 10 times):

• Sear ribs on sauté function (high heat, 3 minutes per side)
• 1 cup beef broth, 1/2 cup dry red wine, aromatics
• 50 minutes high pressure, 15 minutes natural release
• Strain liquid, reduce on sauté function for 10 minutes

Results: Consistently perfect. Every batch produced ribs that were fall-off-the-bone tender with a rich, gelatinous sauce. The pressure cooking breaks down connective tissue more reliably than oven braising. The sauté function for searing and sauce reduction means one pot start to finish — less cleanup.

Hard-Boiled Eggs: The 5-6-5 Method

Keto breakfasts often feature hard-boiled eggs, and the Instant Pot makes the best ones I’ve ever produced:

• 1 cup water, eggs on trivet
• 5 minutes high pressure, 6 minutes natural release, 5 minutes ice bath

Results: Perfectly cooked eggs with creamy yellow yolks (never green) and shells that slide off in two pieces. I tested this with 6 dozen eggs over 5 months and the consistency is remarkable. The pressure cooking apparently causes the egg white to separate from the shell membrane, making peeling effortless.

For comparison, stovetop boiled eggs from the same carton were inconsistent — some peeled easily, some stuck to the shell. The Instant Pot method works every time.

Keto Cheesecake: The Surprising Win

I was skeptical about pressure cooker cheesecake, but after 6 test batches, I’m a convert:

• 7-inch springform pan fits perfectly in the 6-quart
• 2 cups water in the bottom, pan on trivet
• 35 minutes high pressure, natural release for 10 minutes
• Cool to room temp, then chill 4+ hours

Results: Creamy, dense, crack-free cheesecake every time. The pressure cooker creates a gentle, even heat that’s actually superior to oven baking for cheesecake. No water bath needed, no cracks, no overcooked edges. The center is perfectly silky.

My keto cheesecake recipe: 2 packages cream cheese, 3 eggs, 1/2 cup erythritol, 1 tsp vanilla, 1 tbsp lemon juice. Blend, pour into crust (almond flour + butter), pressure cook. It’s become my go-to keto dessert for dinner parties.

Functions I Actually Used (and Didn’t)

The “7-in-1” label means it’s a pressure cooker, slow cooker, rice cooker, steamer, sauté pan, yogurt maker, and warmer. After 5 months, here’s my actual usage:

Pressure cooking: 90% of my usage. Bone broth, meats, eggs, cheesecake. This is why you buy an Instant Pot. Sauté: Used in almost every pressure cook recipe for searing meat. Very useful, gets hot enough for a proper sear. Slow cooker: Used twice in 5 months. The low setting runs hotter than my dedicated Crock-Pot (~190°F vs ~170°F), which isn’t ideal for true low-and-slow rendering. I kept my slow cooker for carnitas. Rice cooker: Never used (keto = no rice). Would be useful for cauliflower rice, but that cooks in 3 minutes on the stovetop. Steamer: Used once for salmon. Worked fine but I prefer pan-searing salmon. Yogurt maker: Never used. May try keto yogurt eventually. Warmer: Used automatically after pressure cooking. Works fine for keeping food hot until serving.

Bottom line: You’re really buying this for the pressure cooker function. The other modes are bonuses that you may or may not use. If you already have a slow cooker you love, you won’t use the Instant Pot’s slow cooker mode.

Durability After 5 Months

The Instant Pot Duo 7-in-1 has held up perfectly after 5 months of weekly use:

• Inner pot: No warping, no staining, no scratches. The stainless steel is genuinely durable. I’ve cooked acidic foods (tomato-based keto sauces) with no reaction.
• Sealing ring: Absorbs food smells. After 5 months, it smells like beef broth permanently. I bought a second ring ($10) for sweet foods so my cheesecake doesn’t taste like pork. This is a known Instant Pot issue, not a defect.
• Lid: Still seals perfectly. The float valve and pressure release work as smoothly as day one.
• Exterior: No discoloration or damage. The stainless steel exterior wipes clean easily.
• Display and buttons: All buttons still responsive, display still clear.

6-Quart vs. 8-Quart

I tested the 6-quart and have zero regrets. It fits:

• 3-pound pork shoulder (perfect for 1-2 weeks of pulled pork)
• 4 pounds of short ribs (4-6 servings)
• Enough bone broth ingredients for 8 cups of finished broth
• 6-egg batches of hard-boiled eggs
• One 7-inch springform pan for cheesecake

The 8-quart would be better if you:

• Cook for 4+ people regularly
• Make bone broth in very large quantities (more than 8 cups at a time)
• Want to cook whole chickens larger than 5 pounds

For 1-2 person keto meal prep, the 6-quart is ideal. It’s also $10 cheaper and takes up less counter space — important if you also have an air fryer and other keto appliances.

Final Verdict

The Instant Pot Duo 7-in-1 is the second most-used keto appliance in my kitchen (after the Vitamix for bulletproof coffee). It improved my meal prep from a 4-hour Sunday chore into a 90-minute efficient process. The bone broth alone justifies the purchase — better quality, 1/15th the time, and a fraction of the cost of store-bought.

Rating: 4.6/5 stars

It loses points for the sealing ring odor absorption (easily solved with a second ring, but still an extra purchase), the slow cooker mode running too hot for true low-and-slow, and the fact that the “7-in-1” marketing oversells features most keto cooks won’t use. But as a pressure cooker for keto batch cooking, it’s excellent.

Perfect for: Keto meal preppers, bone broth makers, anyone who cooks large cuts of meat weekly, busy people who need fast batch cooking Skip it if: You cook single servings only, you already have a pressure cooker you like, or your kitchen has very limited storage space
