Step-by-Step: How to Make Sous Vide Egg and Potato Breakfast Jars
1. Prepare the Potato Purée
Begin by peeling and chopping the russet potato into medium-sized chunks. Boil the potatoes with peeled garlic cloves and a pinch of salt until fork-tender (about 15 to 20 minutes). Strain well and transfer to a mixing bowl. Use a masher, ricer, or fork to mash the potatoes until smooth.
In a separate bowl, melt the butter and fold it along with the cream into the potatoes. Season generously with salt and pepper. For supreme smoothness, press the mixture through a fine mesh sieve or whip with an electric hand mixer until silky.
Pro Tip: For extra richness, swap in crème fraîche or even some cheese (Parmesan or Gruyère) with the mashed potatoes.
2. Assemble the Jars
- Fill each jar about one-third full with potato purée. Aim for a smooth, flat surface to prevent the egg from seeping to the bottom.
- Carefully crack one egg on top of the purée in each jar.
- Wipe the rim clean and screw on the lids finger-tight (do not overtighten; this allows air to escape and prevents jars from cracking during cooking).
3. Cook Sous Vide
Heat your sous vide water bath to 149°F (65°C). Gently lower the jars into the bath with tongs, ensuring they are fully submerged.
Cook for 30 minutes; this yields an egg with set whites and a runny, custard-like yolk.
For other textures, adjust cooking time slightly: longer for firmer yolks, shorter for very soft-set eggs.
4. Serve and Savor
- Carefully remove jars from the bath.
- Garnish each with a sprinkle of freshly chopped chives (or parsley, cilantro). Optionally, finish with flaky sea salt or a drizzle of olive oil.
- Stir together in the jar, then enjoy with toast or baguette slices for dipping and scooping.
Customization and Variations
- Herbs: Try chives, parsley, tarragon, or cilantro for fresh flavor.
- Cheese: Blend grated Parmesan, aged cheddar, or goat cheese into the potato purée.
- Truffle Taste: Finish with a touch of truffle salt or oil for luxury.
- Vegetarian Boost: Add sautéed spinach or sautéed mushrooms to the jar before adding egg.
- Protein: Layer in crumbled bacon or smoked salmon for a heartier meal.
Troubleshooting Common Problems

Frequently Asked Questions (FAQs)
Q: Can I use leftover mashed potatoes for this recipe?
Yes. Leftover mashed potatoes work beautifully; simply reheat, add a splash of cream and butter to rehydrate, then proceed. Make sure the purée is very smooth before piping.
Q: Do I need a sous vide circulator?
Sous vide is recommended for consistent egg texture, but you can use a steamer or a pot with a trivet and gently steam the jars. Precise temperature control is key.
Q: How do I avoid breaking the jars in the water bath?
Seal the jars finger-tight, not overly tight. Start with room temperature jars and avoid drastic temperature changes.
Q: Can I make these breakfast jars ahead of time?
Yes. Assemble up to two days ahead, store in the fridge, and reheat gently in simmering water before serving.
Q: What bread pairs best?
Baguette, sourdough, or rustic whole-grain breads are ideal for dunking into the creamy potato and egg mixture.
Storage and Make-Ahead Tips
- Tightly sealed jars keep up to 3 days refrigerated.
- Reheat gently in a simmering water bath (not boiling) for best results.
- Do not freeze—the texture of potatoes and eggs will suffer upon thawing.
