Each bowl of this slow cooker miso congee delivers 27 grams of plant-based protein from a combination of extra-firm tofu and shelled edamame, making it one of the most protein-dense porridges you can wake up to. The rice breaks down overnight into a silky, easily digestible base while the tofu absorbs the savory depth of white miso and ginger. At just 325 calories per generous serving, it provides serious nutritional substance without the heaviness that makes mornings difficult on GLP-1 medications.

Japanese okayu — rice porridge — is one of the gentlest breakfast traditions in the world, and this version leans into that comfort while significantly boosting the protein. White miso adds a round, slightly sweet umami backbone that pairs beautifully with fresh ginger and a whisper of sesame. The edamame stirred in at the end provides bright color, a slight pop of texture against the creamy rice, and a clean plant-protein boost that keeps the bowl interesting from first spoonful to last.

For GLP-1 users, congee is a near-perfect breakfast format. The slow-cooked rice is broken down into a form that moves gently through a system where gastric emptying is already slowed. Small portions feel satisfying because the porridge is warm, savory, and nutrient-dense rather than relying on volume. The overnight slow cooker method means zero morning effort — you wake up to a finished breakfast that simply needs a stir and a garnish.

Why This Works on GLP-1

With 27 grams of protein per serving, this congee helps protect lean muscle mass during the weight loss phase that accompanies GLP-1 medications like Mounjaro and Wegovy. Muscle preservation is one of the most important nutritional goals while on these medications, because rapid weight loss without adequate protein can lead to significant lean tissue loss. The combination of tofu and edamame provides all essential amino acids when eaten together, making this a complete protein breakfast without any animal products. Starting your day with this level of protein also helps stabilize blood sugar through the morning, complementing the glucose-regulating effects of your medication.

The soft, porridge-like texture is particularly well suited to the slowed gastric emptying that GLP-1 medications cause. Unlike dense or fibrous breakfasts that can sit uncomfortably, congee is already partially broken down by long cooking, reducing the digestive workload. The ginger in the recipe also serves a functional purpose — it has well-documented anti-nausea properties that can help ease the morning queasiness some users experience, especially during dose adjustments.

At under 400 calories per bowl, this breakfast leaves comfortable room for the rest of your day's nutrition without the caloric density that leads to discomfort. The moderate fiber from edamame and rice supports regularity without the bloating that high-fiber cereals or raw vegetable breakfasts can trigger. White miso also contains beneficial probiotics that support gut health, an area of increasing interest for people on GLP-1 therapy.

Ingredients (serves 4)

For the congee base:

  • 3/4 cup (140g) short-grain Japanese rice (sushi rice), rinsed well
  • 5 cups (1.2L) low-sodium vegetable broth
  • 1 cup (240ml) water
  • 1 tablespoon fresh ginger, peeled and finely grated
  • 2 cloves garlic, minced
  • 1 teaspoon toasted sesame oil

For the protein:

  • 20 oz (565g) extra-firm tofu, drained and pressed, cut into 1/2-inch cubes
  • 2 cups (310g) frozen shelled edamame

For the miso seasoning:

  • 3 tablespoons (50g) white miso paste (shiro miso)
  • 1 tablespoon low-sodium soy sauce
  • 1 teaspoon rice vinegar

For serving:

  • 2 green onions, thinly sliced
  • 1 sheet nori, cut into thin strips
  • 1 teaspoon toasted sesame seeds
  • Shichimi togarashi (optional, for those who tolerate mild spice)

Instructions

Prepare the slow cooker base (evening, 5 minutes):

  1. Rinse the short-grain rice under cold water until the water runs mostly clear — this removes excess surface starch and prevents the congee from becoming gummy rather than silky. Drain well.
  2. Add the rinsed rice, vegetable broth, water, grated ginger, minced garlic, and sesame oil to the slow cooker. Stir to combine evenly.
  3. Scatter the pressed tofu cubes over the top of the rice mixture. The tofu will slowly absorb the miso-ginger broth as it cooks, becoming deeply flavored throughout.
  4. Cover and set the slow cooker to LOW for 7–8 hours, or HIGH for 4 hours if preparing in the early morning. The rice should break down completely into a thick, creamy porridge.

Finish the congee (morning, 10 minutes):

  1. When the congee is done, the rice should be fully broken down into a smooth, thick porridge. If it looks too thick, stir in a splash of hot water or broth — congee thickens considerably as it sits, so adjust to your preferred consistency.
  2. In a small bowl, whisk the white miso paste with 2 tablespoons of the hot congee liquid until completely smooth. This prevents the miso from clumping and distributes its flavor evenly. Stir the miso mixture, soy sauce, and rice vinegar into the congee.
  3. Add the frozen edamame directly to the slow cooker, stir gently, and replace the lid. Let sit for 5 minutes on the warm setting — the residual heat will thaw and warm the edamame without overcooking them, keeping their bright green color and slight bite.
  4. Taste and adjust seasoning. The miso and soy sauce should provide enough salt, but a tiny splash more rice vinegar can brighten everything if it tastes flat.

Serve:

  1. Ladle the congee into bowls. Top each serving with sliced green onions, nori strips, a pinch of sesame seeds, and shichimi togarashi if desired. Serve immediately while warm and creamy.

Practical Notes

Meal prep storage works beautifully. Portion the finished congee into individual containers and refrigerate for up to 4 days. It will thicken significantly in the fridge — simply stir in 2–3 tablespoons of water or broth when reheating in the microwave, about 90 seconds per portion. Add fresh green onion and nori only when serving to keep them crisp.

Press your tofu properly for the best texture. Wrap the tofu block in a clean kitchen towel, place it on a plate, and set something heavy on top (a cast iron skillet works perfectly) for at least 15 minutes before cubing. Well-pressed tofu holds its shape in the slow cooker and absorbs more of the miso-ginger broth, giving you more flavor in every bite.

The miso goes in at the end — never at the start. Miso's beneficial probiotics and delicate flavor are destroyed by prolonged high heat. Stirring it in after cooking preserves both the health benefits and the nuanced, slightly sweet umami character. This is standard practice in Japanese cooking and makes a noticeable difference in the finished bowl.

For very small appetites, halve the portion. If you are in the early weeks of Ozempic or another GLP-1 medication and your appetite is significantly reduced, a half-portion (about 3/4 cup) still delivers over 13 grams of protein. Pair it with a small glass of protein-fortified soy milk to reach 20 grams without adding volume to your bowl.

Swap the grain for variety. Steel-cut oats work surprisingly well as a substitute for the rice, creating a savory oat porridge with a slightly nuttier character. Use the same liquid ratio and cooking time. Brown rice also works but increase the liquid by 1/2 cup and expect a slightly chewier, less silky result.

Frequently Asked Questions

Will the soft texture of congee cause blood sugar spikes since the rice is so broken down?
Congee made from white rice alone can raise blood sugar relatively quickly, but this version is significantly different from plain rice porridge. The 27 grams of protein from tofu and edamame substantially slow glucose absorption, as does the fat content from the tofu and sesame oil. The overall glycemic impact of a mixed meal like this is much lower than the rice component alone would suggest. For GLP-1 users, the medication itself also helps regulate post-meal blood sugar, so this combination works well. If you are still concerned, using short-grain brown rice will lower the glycemic response further, though it changes the texture.
Can I use silken tofu instead of extra-firm?
You can, but the result will be quite different. Silken tofu will dissolve into the congee during the long cooking time, creating an even creamier texture but with no distinct tofu pieces. If you prefer visible cubes of tofu in your porridge, stick with extra-firm and add it at the start as directed. A middle-ground approach is to blend half the tofu (silken) into the broth for creaminess and cube the other half (extra-firm) for texture. The protein content remains the same regardless of tofu type.
How long does this keep, and can I freeze individual portions?
Refrigerated congee keeps well for 4 days in airtight containers. It freezes acceptably for up to 2 months, though the texture becomes slightly grainier after thawing — the rice starches retrograde during freezing and do not fully return to their original silkiness. To freeze, portion into individual containers leaving a half-inch of headspace, as the porridge expands. Thaw overnight in the refrigerator and reheat with an extra splash of broth, stirring well. The edamame holds up to freezing better than the rice does.
What if I can only eat a few spoonfuls in the morning on my GLP-1 medication?
This is very common, especially in the first weeks or after a dose increase. Congee is actually one of the best foods for this situation because even a few spoonfuls deliver meaningful nutrition in a form that is extremely gentle on a slow-moving digestive system. Warm the amount you can manage — even a quarter portion gives you nearly 7 grams of protein. Keep the rest refrigerated and try eating another small portion mid-morning when your appetite may have returned slightly. The warm temperature and soft texture tend to be better tolerated than cold or crunchy breakfast options during periods of significant appetite suppression.
My slow cooker runs hot and tends to burn things on the bottom overnight. How do I prevent this?
Slow cookers vary significantly in temperature, and congee is particularly prone to sticking because of the starchy rice. First, make sure you use the LOW setting — high will almost certainly scorch the bottom over 7–8 hours. Lightly greasing the insert with cooking spray before adding ingredients creates a thin barrier. You can also place the tofu cubes on the bottom as a buffer layer between the rice and the hot surface. If your slow cooker still runs hot, try reducing the cook time to 6 hours, or use a programmable model that switches to warm automatically. A slow cooker liner bag is another reliable option for easy cleanup and scorch prevention.
