Keto Mississippi Pot Roast (Gluten-Free Recipe)

Good news: Mississippi Pot Roast is already almost keto. Chuck roast, butter, and pepperoncini peppers are all zero-carb. The only issue is the two dry seasoning packets. Most commercial ranch and au jus mixes contain small amounts of sugar, starch, and sometimes gluten from wheat-based fillers.

This guide shows you exactly what is in those packets, which brands are safe as-is, and how to make a homemade replacement that is fully keto, fully gluten-free, and arguably better than the original. The beef still falls apart. The sauce is still rich and tangy. Nothing is compromised.

If you are new to the dish, start with the original Mississippi Pot Roast recipe to understand the base. Then come back here for the keto adaptation.

Is the Original Mississippi Pot Roast Keto?

Almost. Here is a breakdown of each ingredient in the original recipe:

Ingredient	Keto?	Gluten-free?	Notes
Chuck roast	Yes	Yes	Zero carbs, high fat and protein
Unsalted butter	Yes	Yes	Zero carbs
Pepperoncini peppers	Yes	Yes	Under 1g carbs per serving
Dry ranch seasoning packet	Mostly	Sometimes	1 to 2g carbs per serving, may contain gluten
Au jus gravy mix packet	Mostly	Rarely	1 to 2g carbs per serving, often contains wheat starch

For strict keto (under 20g net carbs per day), the packets add roughly 2 to 4g of carbs per serving from the whole batch. For most people following a relaxed keto or low-carb approach, the original recipe with standard packets is fine. For strict keto, celiac disease, or non-celiac gluten sensitivity, the homemade seasoning blend below removes the uncertainty entirely.

What Is Actually in the Seasoning Packets

Hidden Valley Original Ranch Dressing Mix (dry)

Ingredients include maltodextrin, salt, buttermilk, garlic, onion, spices, and natural flavours. Maltodextrin is a starch-based filler that contributes carbohydrates and can spike blood sugar similarly to sugar despite not being listed as sugar. One packet (1 oz) contains approximately 4g of carbohydrates total across the whole batch, or under 1g per serving for a 6-serving recipe. Hidden Valley Ranch is not certified gluten-free.

McCormick Au Jus Gravy Mix

Ingredients typically include wheat flour or wheat starch as a thickening agent, which makes most au jus packets unsuitable for celiac disease. The carbohydrate content is low (approximately 2g per serving for the whole batch) but the gluten from wheat is the primary concern for gluten-sensitive readers.

Formulations change. Manufacturers update their recipes without notice. Always read the current label before purchasing rather than relying on older information online. The homemade blend below removes the need to check labels at all.

Brands That Are Keto and Gluten-Free

If you prefer to use packets rather than making your own blend, these options are generally safer choices. Always verify the current label since formulations change:

Ranch seasoning

• Simply Organic Ranch Dressing Mix – certified gluten-free, lower in fillers than Hidden Valley
• Primal Palate New Bae Seasoning – paleo and gluten-free, similar flavour profile to ranch
• Wholesome Yum Keto Ranch Seasoning – designed specifically for keto, no maltodextrin

Au jus replacement

Finding a gluten-free au jus packet is harder because wheat starch is the standard thickener. The homemade blend below is more reliable than hunting for a certified GF packet product, but these are worth checking at your local store:

• Pacific Foods Organic Beef Broth powder – not a true au jus replacement but works as a base
• Primal Kitchen No Dairy Beef Broth packets – gluten-free, though the flavour is milder than au jus mix

Homemade Keto Seasoning Blend

This is the cleanest approach and the one most keto and gluten-free cooks settle on after trying the packet alternatives. It takes 3 minutes to mix, uses pantry staples, produces no mystery ingredients, and tastes at least as good as the commercial packets.

Keto ranch seasoning blend (replaces 1 ranch packet)

• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon dried dill
• 1 teaspoon dried parsley
• 0.5 teaspoon dried chives
• 0.5 teaspoon fine sea salt
• 0.25 teaspoon black pepper
• 0.25 teaspoon dried mustard powder

Keto au jus blend (replaces 1 au jus packet)

• 1 tablespoon Worcestershire sauce (check label for GF – Lea and Perrins is traditionally GF in the US)
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 0.5 teaspoon smoked paprika
• 0.5 teaspoon fine sea salt
• 0.25 teaspoon black pepper
• 0.25 teaspoon beef bouillon granules (check label for GF)

Mix each blend separately in a small bowl before adding to the slow cooker. Sprinkle the ranch blend over the roast first, then the au jus blend on top. Add the Worcestershire sauce directly to the pot along with the dry au jus ingredients.

Make the seasoning blends in bulk. Multiply each recipe by 4 or 5 and store in small airtight jars. Label each jar with the equivalent measurement (one jar equals one packet). You will always have keto Mississippi seasoning ready to go without mixing from scratch each time.

Full Keto Mississippi Pot Roast Ingredients

• 3 to 4 lb chuck roast – the best cut for this recipe. See our full breakdown: best cut of meat for Mississippi Pot Roast. Chuck roast is already keto-perfect: high fat, zero carbs.
• Keto ranch seasoning blend (recipe above) – or a certified GF ranch packet
• Keto au jus blend (recipe above) – or a verified GF au jus packet
• 4 tablespoons unsalted butter – zero carbs, fully keto
• 6 to 8 whole pepperoncini peppers – under 1g net carbs per serving
• 1 tablespoon Worcestershire sauce – included in the au jus blend above

Total estimated net carbs per serving: under 2g (for a 6-serving batch using the homemade blends)

Step-by-Step Instructions

Step 1 – Mix the seasoning blends

In a small bowl, combine all the keto ranch blend ingredients and mix well. In a separate small bowl, combine all the dry keto au jus blend ingredients. Keep the Worcestershire sauce separate for now.

Step 2 – Season the roast

Pat the chuck roast dry with paper towels and place in the bottom of a 6-quart slow cooker. Sprinkle the ranch blend evenly over the top of the roast, then sprinkle the dry au jus blend over that. Add the Worcestershire sauce by drizzling it over the seasoning.

Step 3 – Add butter and peppers

Place the butter pats directly on top of the seasoning. Arrange the pepperoncini peppers around and on top of the roast. Add 2 tablespoons of the jar brine if you want extra tang. Do not add water or broth.

Step 4 – Cook on LOW

Cover and cook on LOW for 8 hours. Do not lift the lid during cooking. The homemade seasoning blend behaves identically to the packets in the slow cooker. No adjustments needed to the cook time or method.

Step 5 – Shred and serve

After 8 hours the roast should pull apart effortlessly with two forks. Shred the beef directly in the slow cooker, toss through the cooking juices, and taste. Adjust salt if needed. Serve over cauliflower mash, zucchini noodles, or with roasted vegetables.

Keto Sides to Serve with It

The cooking jus is the sauce. You want something to pour it over or soak it up. For keto:

• Cauliflower mash – the number one keto substitute for mashed potatoes. Make it generously with butter and cream cheese so it is rich enough to match the beef. Season well with salt and garlic powder.
• Zucchini noodles (zoodles) – toss the shredded beef and cooking jus through lightly sauteed zucchini noodles. Quick, low-carb, and surprisingly satisfying.
• Roasted cauliflower florets – roast at 425°F with olive oil and salt until golden. The caramelised edges hold up well against the rich sauce.
• Spaghetti squash – fork-shredded spaghetti squash with the beef and jus is a full keto meal in one bowl.
• Roasted broccoli – crispy edges from a high oven temperature, simple olive oil and salt, ready in 20 minutes.
• Creamed spinach – the creaminess complements the tangy sauce and it is naturally low-carb.
• Lettuce wraps – for a lighter lunch option, serve the shredded beef in butter lettuce cups with pickled onion and a drizzle of the jus.
